Abstrak :
Rugi-rugi atau losses adalah hilangnya sejumlah energy, yang dibangkitkan sehingga mengurangi jumlah energy yang dapat dijual kepada konsumen sehingga berpengaruh pada tingkat profitibilitas perusahaan bersangkutan.Besar kecilnya rugi-rugi dari suatu system tenaga listrik menunjukkan tingkat efisiensi system tersebut, makin rendah prosentase rugi-rugi yang terjadi makin efisien system tersebut.Rugi-rugi dari trafo akan berbeda, walaupun kapasitas (rated) kedua trafo tersebut sama dan menimbulkan perbedaan biaya rugi-rugi.Seberapa besar biaya yang ditimbulkan oleh perbedaan rugi-rugi daya trafo tersebut akan dievaluasi dalam tugas akhir ini.Biaya-biaya tersebut adalah biaya rugi-rugi daya tanpa beban, biaya rugi ? rugi daya berbeban dan biaya investasi.Dengan demikian dari hasil evaluasi dua buah trafo distribusi, dapat dipilih trafo yang menguntungkan. ......losses is the loss of energy, it is raised, there by reducing the amount of energy that can be sold to consumers so that the effect on company profitability level itself.Amount loss of a power system shows the level of efficiency of these systems, the lower the percentage of loss-loss is the more efficient the system tersebut. loss from the transformer will be different, although the capacity (rated) the two transformers are equal and lead to differences in the cost of large-loss rugi.Seberapa costs caused by differences in power transformer losses will be evaluated in the task ini. end-cost is the cost of power loss without the burden, expense and loss -loss of power load and thus cost of evaluation results investation .Within two distribution transformers, transformer that benefit can be selected.

Abstrak :
Arsitektur berperan dalam menciptakan lingkungan untuk memenuhi kebutuhan manusia. Salah satu tujuan arsitektur adalah menciptakan lingkungan yang berkualitas dimana dapat memenuhi kebutuhan manusia tanpa merusak atau membebani lingkungan dan alam. Baik lingkungan buatan maupun alam harus ditata secara seimbang agar tercipta kehidupan yang harmonis. Salah satu faktor penting untuk menciptakan kehidupan yang harmonis adalah penataan energi. Berbagai cara arsitektur mewujudkan bentuk penataan energi yang efisien dan efektif, salah satunya adalah penggunaan energi alternatif. Skripsi ini membahas tentang pemanfaatan tenaga angin yang dikonversi menjadi energi yang lebih bermanfaat dengan menggunakan turbin angin dan pembahasan difokuskan dari sudut pandang arsitektur dan lingkungan. ......Architecture plays a role in creating an environment to meet human needs. One of the goals of architecture is to create a quality environment in which to meet human needs without damaging or burdening the environment and nature. Both the artificial and the natural environment should be arranged in a balanced way in order to create a harmonious life. One of important factors to create a harmonious life is the arrangement of energy. Various ways in architecture to realize arrangement of energy which efficiently and effectively, one of which is the use of alternative energy. This thesis discusses the use of wind power converted into useful energy using wind turbines and focuses discussion point of view of architectural and environmental.

Abstrak :
The aim of the book is to improve conventional building design in Southeast Europe. This is done with proposing conceptual guidelines for designing energy-efficient buildings for different geographic regions of Serbia. The focus is on climate-appropriate design of building envelopes. To adress sustainability, economical, environmental and social aspects are evaluated. The body is divided into three main chapters: traditional houses, the existing housing stock, and design patterns for future buildings. The conclusions and the methodology can be applied in the rest of Southeast Europe, since Serbia has a unique position in the middle of the region, covering different geographical areas that spread far out of Serbias borders.

Abstrak :
This book reports on the latest research and applications in the fields of sustainable manufacturing and remanufacturing, as well as process planning and optimization technologies. It introduces innovative algorithms, methodologies, industrial case studies and applications. It focuses on two topics: sustainable manufacturing for machining technologies and remanufacturing of waste electronic equipment, and various methods are covered for each one, including macro process planning, dynamic scheduling, selective disassembly planning and cloud-based disassembly planning. The experimental analysis provided for every method explains the benefits, as well as how they are sustainable for various real-world applications. This book is a valuable resource for researchers in sustainable manufacturing, remanufacturing and product lifecycle management communities, as well as practicing engineers and decision-makers in industry and all those interested in sustainable product development. It is also useful reading material for postgraduates and academics wanting to conduct relevant research, and a reference resource for manufacturing engineers developing innovative tools and methodologies.

Medved, Saso
Abstrak :
This book presents cutting-edge work on the energy efficiency and environmental sustainability of buildings, examining EU policies, regulations and technologies for complex systems such as passive buildings, sustainable buildings and, as part of the Energy Performance of Building Directive (EPBD), nearly Zero Energy Buildings (nZEB) requirements. It explores a wide range of topics, including indoor environment requirements, building physics, in-situ experiments to determine the thermal properties of buildings, nZEB requirements, building service technology, and methods of evaluating energy efficiency and environmental impacts. It also provides an overview of the best available technologies for nZEB, including those for the rational use of energy, utilization of renewable energy sources, EPBD systems and calculation methods. This book is a valuable resource for students, researchers and practitioners of urban planning, and architecture, civil and mechanical engineering.

Abstrak :
This book focuses on scheduling algorithms for parallel applications on heterogeneous distributed systems, and addresses key scheduling requirements – high performance, low energy consumption, real time, and high reliability – from the perspectives of both theory and engineering practice. Further, it examines two typical application cases in automotive cyber-physical systems and cloud systems in detail, and discusses scheduling challenges in connection with resource costs, reliability and low energy. The book offers a comprehensive and systematic treatment of high-performance, low energy consumption, and high reliability issues on heterogeneous distributed systems, making it a particularly valuable resource for researchers, engineers and graduate students in the fields of computer science and engineering, information science and engineering, and automotive engineering, etc. The wealth of motivational examples with figures and tables make it easy to understand.
