Production and Reproduction Performances and Constraints of local and exotic Layer Chicken in Ethiopia
Studienarbeit aus dem Jahr 2020 im Fachbereich Agrarwissenschaften, Sprache: Deutsch, Abstract: This review is done on comparative evaluation of production and reproduction performances and constraints of local and exotic layer chicken in Ethiopia. Poultry is by far the largest group of livestock species in the world and chicken largely dominate flock composition. In Ethiopia; except chickens other poultry species production is not practicing that they are living in their natural habitat. The poultry sector in Ethiopia can be characterized into three major production systems based on some selected parameters such as breed, flock size, housing, feed, health, technology and bio-security. These are large commercial or intensive, small scale commercial or semi-intensive and free range or village back yard poultry production system. However, the majority of chicken production system in Ethiopia remains as village or back scavenging system which consist the indigenous chickens as major. In Ethiopia, poultry industry plays a significant role in the supply of human food (eggs and meat) in rural and urban area and as a source of income, especially to small holder farmers. Mean number of egg production was higher for exotic breed than local chicken ecotypes. Higher egg production and better reproductive life span is obtained from exotic chickens than local ones. Moreover, overall survival rate of exotic and crossbred chickens are found comparable to local chicken. Therefore, introducing Bovans Brown chickens having better productive and reproductive performance is important to enhance productivity. Non-genetic factors should also be considered to improve the performance of existing local chicken population. But, feed shortage, disease and other critical gaps that need to be filled by the institutions of research and development to improve the productive performance of exotic chicken breed in Ethiopia.

Wireless Sensor Networks. Routing Protocol Overview
Document from the year 2020 in the subject Engineering - Computer Engineering, language: English, abstract: Sensor nodes have restricted storage, computational and energy resources, these restrictions place a limit on the types of deployable routing mechanisms. Routing protocol disseminates information that enables the sensor nodes to select routes to communicate with other nodes on the network and the choice of the route is determined by the routing algorithms. Thus the routing protocol helps the nodes to gain knowledge about the topology of the network to which it is attached directly. There are mainly two types of routing processes: one is static routing and the other is dynamic routing. In a static routing, the routing tables are set up in a static manner in the nodes. The network routes for the packet are initially set between the nodes. However, if any node on the specified route fails, the data may not reach the destination. In a dynamic routing, routing tables in the routers often change whenever the possible routes change. Dynamic routing is more suitable as the nodes in WSNs may frequently change their position and die at any moment. The routing protocols are classified into single hop and multi hop routing. In a single hop routing, sensor node directly communicates with the sink to share the gathered information. Energy consumption is high in the network using single hop protocol. In multi hop routing, data is routed through the intermediate nodes to the base station. Each node transfers sensed data to the immediate node which in turn transfers the data to the next immediate node and finally the data reaches the base station. Energy consumption in this kind of routing protocol is less and thus the lifetime of the nodes is high. The major challenge to the efficient operation of wireless sensor network lies in its ability to deliver the sensed information from the nodes to the sink within the specific time duration without the loss of data packets
Multi Purpose Seedling Need Assessment. The Case of Wolaita Zone, especially Humbo, Damot Woyde, Sodo Zuriya and Sodo Ketema
Research Paper (postgraduate) from the year 2011 in the subject Forestry / Forestry Economics, grade: 1, course: Forest management, language: English, abstract: The objectives of the study were, to assess the need of trees and coffee seedlings of the selected worada's, to know the yearly accepting potential of seedlings of the selected area, to assess the availability of Permanent tree nursery at study worada's and to assess the perception of community towards the establishment of permanent seedling nursery in their vicinity. Deforestation is a contributor to global warming and is often cited as one of the major causes of the enhanced greenhouse effect. According to the Intergovernmental Panel on Climate Change, deforestation mainly in tropical areas, could account for up to one-third of total anthropogenic carbon dioxide emissions. But recent calculations suggest that carbon dioxide emissions from deforestation and forest degradation contribute about 12% of total anthropogenic carbon dioxide emissions with a range from 6 to 17%. Plants remove carbon in the form of carbon dioxide from the atmosphere during the process of photosynthesis. Ethiopia is one of the countries where forest resources degradation exhibits primarily due to population explosion. The forest policy is also not said to be effective in forest policy regards. At present it is facing a serious ecological problem triggered mainly by the fast growth of population which led to destructive nature of land resource uses involving deforestation even without leaving time space for regeneration of natural forests. The situation exposes the land to serious land degradation altering local environment and micro climate. To change this situation urgent natural resource management primarily forest management strategies intervention is required.

Data Power
In recent years, popular media has inundated audiences with sensationalized headlines recounting data breaches, new forms of surveillance and other dangers of our digital age. Despite their regularity, such accounts treat each case as unprecedented and unique. This book proposes a radical rethinking of the history, present and future of our relations with the digital, spatial technologies that increasingly mediate our everyday lives. From smartphones to surveillance cameras, to navigational satellites, these new technologies offer visions of integrated, smooth and efficient societies, even as they directly conflict with the ways users experience them. Recognizing the potential for both control and liberation, the authors argue against both acquiescence to and rejection of these technologies. Through intentional use of the very systems that monitor them, activists from Charlottesville to Hong Kong are subverting, resisting and repurposing geographic technologies. Using examples as varied as writings on the first telephones to the experiences of a feminist collective for migrant women in Spain, the authors present a revolution of everyday technologies. In the face of the seemingly inevitable circumstances, these technologies allow us to create new spaces of affinity, and a new politics of change.In recent years, popular media have inundated audiences with sensationalised headlines recounting data breaches, new forms of surveillance and other dangers of our digital age.

The Warehouse
'Work hard, have fun, make history' proclaims the slogan on the walls of Amazon's warehouses. This cheerful message hides a reality of digital surveillance, aggressive anti-union tactics and disciplinary layoffs. Reminiscent of the tumult of early industrial capitalism, the hundreds of thousands of workers who help Amazon fulfil consumers' desire are part of an experiment in changing the way we all work. In this book, Alessandro Delfanti takes readers inside Amazon's warehouses to show how technological advancements and managerial techniques subdue the workers rather than empower them, as seen in the sensors that track workers' every movement around the floor and algorithmic systems that re-route orders to circumvent worker sabotage. He looks at new technologies including robotic arms trained by humans and augmented reality goggles, showing that their aim is to standardize, measure and discipline human work rather than replace it. Despite its innovation, Amazon will always need living labor's flexibility and low cost. And as the warehouse is increasingly automated, worker discontent increases. Striking under the banner 'we are not robots', employees have shown that they are acutely aware of such contradictions. The only question remains: how long will it be until Amazon's empire collapses?'Work hard, have fun, make history' proclaims the slogan on the walls of Amazon's warehouses.

Cow Milk Production, Practices and Marketing System of Milk and Milk Products in Sodo Zuria District, Wolaita Zone, Southern Ethiopia
Research Paper (undergraduate) from the year 2019 in the subject Agrarian Studies, grade: 3.78, course: Dairy Production and Management, language: English, abstract: The objectives of the current study were to assess dairy production and marketing systems and to identify constraints and opportunities of dairy production and marketing system in Wolaita zone. Ethiopia possesses the largest livestock population in Africa. Estimates for farmer holding in rural areas indicate that the country has about 60 million heads of cattle, 33 million goats, 31 million sheep, 2 million horses, 9 million donkeys, 1 million mules, and 1 million camels. In Ethiopia, the traditional milk production system and marketing which are dominated by local breeds of low genetic potential for milk production, and accounts for about huge number of the country's total annual milk production. Demand for milk and milk products exceed supply that is expected to increase growth in dairy sector. Milk production systems in Ethiopia is classified into urban, per-urban, and rural. Livestock rising always has been mainly a subsistence activity. They are raised in all of the farming systems of Ethiopia by crop/livestock mixed farmers. Livestock play a vital role in economic development, chiefly as societies change from subsistence agriculture in to cash-based economies. The contribution of the livestock sector is estimated to be about 12% to 16% of the total growth domestic product (TGDP). Only milk and milk products contributed 36%-46% to the house hold income in some areas. In Ethiopia, different type of milk production system can be recognized based on various criteria. Milk production systems can broadly categorized in to urban, peri-urban and rural milk production systems based on location, while based on market location, scale and production intensity, dairy cattle production system can be categorized as traditional small holders, privatized state farms and urban and peri-urban system.

COVID-19 A Systems Perspective
The COVID-19 pandemic is a massive disaster. Returning to normal life will not be a trivial exercise. A systems perspective will be used to understand the COVID-19 disaster and the Return to Life systems that will be developed. In a systems engineering effort for a problem of this magnitude all technologies and products are examined that may be able to address the need and provide a viable solution. This requires massive resources and in the past the US Federal Government and a handful of systems engineering companies performed this type of systems engineering. This is called large complex systems engineering. Examples of large complex systems engineering from the previous century are the Telephone system, Radio and Television, US Space Program, Air Defense, Air Traffic Control, etc. Systems engineering is the mechanism that allows specialists to quickly and effectively communicate their analysis to completely different areas and significantly shift the overall results in a positive direction. This book is in that spirit of an effective systems engineering activity. As time moves on this book will capture the history of the COVID-19 disaster and the struggle to stop it and all other future health disasters in its wake.
Machining Dynamics and Parameters Process Optimization
As we move further into the 21st century, despite the fact that new technologies have emerged, machining remains the key operation to achieve high productivity and precision for high-added value parts in several sectors, but recent advances in computer applications should close the gap between simulations and industrial practices. This book, "Machining Dynamics and Parameters Process Optimization", is oriented toward the different strategies and paths when it comes to increasing productivity and reliability in metal removal processes. The topics include the dynamic characterization of machine tools, experimental dampening techniques, and optimization algorithms combined with signal monitoring.
Numerical and Analytical Methods in Electromagnetics
Like all branches of physics and engineering, electromagnetics relies on mathematical methods for modeling, simulation, and design procedures in all of its aspects (radiation, propagation, scattering, imaging, etc.). Originally, rigorous analytical techniques were the only machinery available to produce any useful results. In the 1960s and 1970s, emphasis was placed on asymptotic techniques, which produced approximations of the fields for very high frequencies when closed-form solutions were not feasible. Later, when computers demonstrated explosive progress, numerical techniques were utilized to develop approximate results of controllable accuracy for arbitrary geometries. In this Special Issue, the most recent advances in the aforementioned approaches are presented to illustrate the state-of-the-art mathematical techniques in electromagnetics.
Algorithms for Fault Detection and Diagnosis
Due to the increasing demand for security and reliability in manufacturing and mechatronic systems, early detection and diagnosis of faults are key points to reduce economic losses caused by unscheduled maintenance and downtimes, to increase safety, to prevent the endangerment of human beings involved in the process operations and to improve reliability and availability of autonomous systems. The development of algorithms for health monitoring and fault and anomaly detection, capable of the early detection, isolation, or even prediction of technical component malfunctioning, is becoming more and more crucial in this context. This Special Issue is devoted to new research efforts and results concerning recent advances and challenges in the application of "Algorithms for Fault Detection and Diagnosis", articulated over a wide range of sectors. The aim is to provide a collection of some of the current state-of-the-art algorithms within this context, together with new advanced theoretical solutions.

Woody Biomass for Bioenergy Production
Woody biomass is most widely used for energy production. In the United States, roughly 2% of the energy consumed annually is generated from wood and wood-derived fuels. Woody biomass needs to be preprocessed and pretreated before it is used for energy production. Preprocessing and pretreatments improve the physical, chemical, and rheological properties, making them more suitable for feeding, handling, storage transportation, and conversion. Mechanical preprocessing technologies such as size reduction and densification, help improve particle size distribution and density. Thermal pretreatment can reduce grinding energy and torrefied ground biomass has improved sphericity, particle surface area, and particle size distribution. This book focuses on several specific topics, such as understanding how forest biomass for biofuels impacts greenhouse gas emissions; mechanical preprocessing, such as densification of forest residue biomass, to improve physical properties such as size, shape, and density; the impact of thermal pretreatment temperatures on woody biomass chemical composition, physical properties, and microstructure for thermochemical conversions such as pyrolysis and gasification; the grindability of torrefied pellets; use of wood for gasification and as a filter for tar removal; and understanding the pyrolysis kinetics of biomass using thermogravimetric analyzers.

Mathematical Models for the Design of Electrical Machines
This book is a comprehensive set of articles reflecting the latest advances and developments in mathematical modeling and the design of electrical machines for different applications. The main models discussed are based on the: i) Maxwell-Fourier method (i.e., the formal resolution of Maxwell's equations by using the separation of variables method and the Fourier's series in 2-D or 3-D with a quasi-Cartesian or polar coordinate system); ii) electrical, thermal and magnetic equivalent circuit; iii) hybrid model. In these different papers, the numerical method and the experimental tests have been used as comparisons or validations.
Integrated Assessment of Climate Change Impacts and Urban Resilience
This book brings together recent research related to urban resilience, in particular, taking into account climate change impacts and hydrological hazards. Due to the complexity of our cities, which are vulnerable and continuously evolving systems, urban resilience should be considered as a transversal and multi-sectorial issue, affecting different urban services, several hazards, and all the steps of the risk management cycle. Within this context, the different pieces of research that form this book deal with the topics of multi-risk and urban resilience assessment, analysis of cascading effects, and the proposal and prioritization of adaptation measures and strategies to cope with climate-related hazards through multi-criteria analysis.
Optical Sensors for Structural Health Monitoring
The evolution and need for the preservation and maintenance of existing structures, recent or historical, has fostered research in the area of structural monitoring, translated into the development of new techniques, equipment and sensors. Early detection of damage and accurate assessment of structural safety requires monitoring systems, the data from which can be used to calibrate numerical models for structural analysis and to assess safety. Data are obtained under real-time conditions, considering a group of parameters related to structural properties, such as stresses, accelerations, deformations and displacements. The analysis of structural properties is particularly relevant when the structure is subjected to extreme events (earthquakes, wind, fire and explosions, among others) or repeated loads (road/rail/air traffic, vibrations induced by equipment and machines), since they affect the structural integrity and put the users at risk. In order to prevent the severe damage and eventual collapse of structures, and consequent human, material and economic losses, the implementation of monitoring systems becomes a valuable tool for today's society. Monitoring of structures is becoming increasingly important, not only as preventive action, but also due to actual economic and sustainability concerns, to ensure a safer and more comfortable built environment.

Research Practice
While other research books offer standard operating procedures, this book provides something more durable in the real world. It's a practical field guide that will give you the encouragement to get started, no matter what your background.-Aarron WalterThis book is not an argument for doing user research. Nor is it a tutorial or toolkit for common methodologies. It won't show you how to run a usability session or recruit users remotely. Research Practice captures the day-to-day of the practice of user research-what it looks like to work with peers and stakeholders, to raise awareness of research, to make tradeoffs, and to build a larger team. This book takes you inside the field of applied user research through the stories and experiences of the people doing the work. Each chapter explores a specific theme: Finding a way in presents the various pathways people take to this field. You'll learn how practitioners navigated from schools, the social sciences, fine arts, and beyond to a career that satisfies and rewards a passion for understanding people.Getting started in a new role demystifies why organizations hire researchers, how to assess a role, the hiring process, and how to start when you land a new job.Building momentum describes the different roles and teams a user researcher might work with, how to build and navigate relationships with colleagues and stakeholders, and the best place within an organization for researchers to make an impact.Sharing the work unpacks what researchers really share by exploring how practitioners build an awareness of research, teach research methodologies, and-yes-disseminate research findings with their teams and organizations.Expanding your practice covers how to navigate growth in both influence and headcount for practitioners, from what research leadership means to how to hire a team to when to operationalize a practice.Overcoming challenges exposes the hard parts that no one tells you about user research, from the loneliness of being a team of one to battling imposter syndrome to advocating for change to taking an ethical stand.Where to go next charts the pathways of a research career through an examination of possible career ladders, perspectives on when it's time to leave a role, and thoughts on where a research leader goes when there isn't a clear next step. If you're in school or considering a career switch, you'll learn what a job in user research might look like. If you're new to the field, you'll see where your career might go and know how to get there. And if you're expanding the size or reach of a practice, you'll understand how others have approached it.
Proposal for a NeuroFuzzy Model to Control Vehicle Traffic
During the last decade, intelligent transportation systems have been widely studied looking for contributions to different types of problems, being one of the most outstanding the efficient and effective management of urban roads. These contributions have been given through the implementation of different advanced computing techniques such as: neural networks, genetic algorithms, multi-objective solutions, application of heuristic models, linear regressions, among others, reaching reliable and adequate results for the studied problems. In this sense, one of the biggest problems faced by city administrators in recent years is that, within certain roads, the regulatory systems and traffic controllers do not operate effectively because they are obsolete to the challenges of this new technological era, because the dynamics of the environment of a road is observed not as an aspect of movement but in relation to how the conditions of the road are changing as time progresses.

Clinical Research on Diabetic Complications
Refrigeration, air conditioning, and heat pumps (RACHP) have an important impact on the final energy uses of many sectors of modern society, such as residential, commercial, industrial, transport, and automotive. Moreover, RACHP also have an important environmental impact due to the working fluids that deplete the stratospheric ozone layer, which are being phased out according to the Montreal Protocol (1989). Last, but not least, high global working potential (GWP), working fluids (directly), and energy consumption (indirectly) are responsible for a non-negligible quota of greenhouse gas (GHG) emissions in the atmosphere, thus impacting climate change.
Les d矇terminants de l’abandon du coton biologique au B矇nin. Cas des communes de Glazou矇, Kandi et P矇hunco
M矇moire (de fin d'矇tudes) de l'ann矇e 2017 dans le domaine Protection de la nature, Conservation du paysage, langue: Fran癟ais, r矇sum矇 Ce m矇moire analyse les facteurs de l'abandon du coton biologique au B矇nin, dans les communes de Glazou矇, Kandi et P矇hunco. Pour y arriver les donn矇es ont 矇t矇 recueillies aupr癡s de 337 producteurs de coton qui auparavant avaient re癟u une formation sur le coton biologique. A l'aide d'un 矇chantillonnage sp矇cifique et raisonn矇, les agriculteurs biologiques identifi矇s sont retenus comme unit矇 d'enqu礙te. Les donn矇es ont 矇t矇 collect矇es avec des entretiens semi-structur矇s et structur矇s. L'analyse factorielle des correspondances multiples (AFCM) des donn矇es a 矇t矇 utilis矇e pour faire ressortir les diff矇rents groupes de producteurs selon leur appr矇ciation du type de coton pratiqu矇 ceux qui pr矇f癡rent le coton conventionnel ? celui non conventionnel, ceux qui pr矇f癡rent le coton conventionnel et ceux qui montrent qu'il n'y a pas de diff矇rence entre les types de coton. Le mod癡le de r矇gression logistique binaire a 矇t矇 faite gr璽ce aux logiciels SPSS et XLSTAT pour d矇terminer les facteurs ? la base de l'abandon du coton biologique. A cela s'ajoutent les diff矇rentes phases d'appr矇ciation de l'adoption de Rogers pour analyser les donn矇es. Il ressort alors des diff矇rentes analyses que le pouvoir explicatif des variables introduites dans le mod癡le est de 0,311 (R2 = 0,311). Ce qui signifie que la variation des variables introduites dans le mod癡le explique 31,11% de la variation de la variable d矇pendante qui est l'abandon du coton biologique. Par ailleurs, les r矇sultats d'estimation du mod癡le montrent que les facteurs significatifs qui influencent l'abandon du coton biologique par les producteurs au b矇nin sont: contact avec les services/agents de vulgarisation, satisfaction par rapport au prix, niveau de fertilit矇 du sol et l'alphab矇tisation. Ces facteurs sont significatifs au seuil de 5%. Il serait alors important d'orienter des s矇ances de formati
Optimization for Decision Making II
In the current context of the electronic governance of society, both administrations and citizens are demanding the greater participation of all the actors involved in the decision-making process relative to the governance of society. This book presents collective works published in the recent Special Issue (SI) entitled "Optimization for Decision Making II". These works give an appropriate response to the new challenges raised, the decision-making process can be done by applying different methods and tools, as well as using different objectives. In real-life problems, the formulation of decision-making problems and the application of optimization techniques to support decisions are particularly complex and a wide range of optimization techniques and methodologies are used to minimize risks, improve quality in making decisions or, in general, to solve problems. In addition, a sensitivity or robustness analysis should be done to validate/analyze the influence of uncertainty regarding decision-making. This book brings together a collection of inter-/multi-disciplinary works applied to the optimization of decision making in a coherent manner.
Emerging Converter Topologies and Control for Grid Connected Photovoltaic Systems
Continuous cost reduction of photovoltaic (PV) systems and the rise of power auctions resulted in the establishment of PV power not only as a green energy source but also as a cost-effective solution to the electricity generation market. Various commercial solutions for grid-connected PV systems are available at any power level, ranging from multi-megawatt utility-scale solar farms to sub-kilowatt residential PV installations. Compared to utility-scale systems, the feasibility of small-scale residential PV installations is still limited by existing technologies that have not yet properly address issues like operation in weak grids, opaque and partial shading, etc. New market drivers such as warranty improvement to match the PV module lifespan, operation voltage range extension for application flexibility, and embedded energy storage for load shifting have again put small-scale PV systems in the spotlight. This Special Issue collects the latest developments in the field of power electronic converter topologies, control, design, and optimization for better energy yield, power conversion efficiency, reliability, and longer lifetime of the small-scale PV systems. This Special Issue will serve as a reference and update for academics, researchers, and practicing engineers to inspire new research and developments that pave the way for next-generation PV systems for residential and small commercial applications.
Short-Term Load Forecasting 2019
Short-term load forecasting (STLF) plays a key role in the formulation of economic, reliable, and secure operating strategies (planning, scheduling, maintenance, and control processes, among others) for a power system and will be significant in the future. However, there is still much to do in these research areas. The deployment of enabling technologies (e.g., smart meters) has made high-granularity data available for many customer segments and to approach many issues, for instance, to make forecasting tasks feasible at several demand aggregation levels. The first challenge is the improvement of STLF models and their performance at new aggregation levels. Moreover, the mix of renewables in the power system, and the necessity to include more flexibility through demand response initiatives have introduced greater uncertainties, which means new challenges for STLF in a more dynamic power system in the 2030-50 horizon. Many techniques have been proposed and applied for STLF, including traditional statistical models and AI techniques. Besides, distribution planning needs, as well as grid modernization, have initiated the development of hierarchical load forecasting. Analogously, the need to face new sources of uncertainty in the power system is giving more importance to probabilistic load forecasting. This Special Issue deals with both fundamental research and practical application research on STLF methodologies to face the challenges of a more distributed and customer-centered power system.
