"The book explores computational and experimental characterization approaches for determining temperature and air flow patterns within data centers. Thermodynamic analyses using the second law to improve energy efficiency are introduced and used in proposing improvements in cooling methodologies. Reduced-order modeling and robust multi-objective design of next generation data centers are discussed."

"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."

"Penelitian ini bertujuan untuk melakukan evaluasi metode Network Breathing sebagai suatu rancangan metode konstruksi jaringan yang adaptif pada komunikasi ZigBee. ZigBee merupakan salah satu protokol komunikasi untuk Wireless Personal Area Network (WPAN) yang dibangun di atas standar IEEE 802.15.4. Karakteristik low power dari ZigBee menjadi salah satu alasan utama dalam pemilihan protokol ini. Suatu metode konstruksi jaringan yang adaptif dapat dirancang untuk mendukung karakteristik ini. Metode ini dimaksudkan untuk membentuk topologi jaringan ZigBee yang senantiasa meminimalkan jumlah router ZigBee yang harus aktif. Metode ini akan menghemat konsumsi energi pada jaringan ZigBee dengan membuat router dalam kondisi tidak aktif ketika tidak ada perangkat akhir dalam jangkauan yang harus dilayani. Rancangan metode ini memiliki prosedur implementasi seperti membentuk jaringan yang bernafas, dan memanfaatkan algoritma shortest path Dijkstra untuk menentukan jumlah minimal dan posisi router yang yang harus aktif sesuai dengan posisi keberadaan perangkat akhir yang harus dilayani. Validasi terhadap rancangan metode ini dilakukan dengan tool perangkat lunak simulasi jaringan NS2, yang menunjukkan penghematan konsumsi energi router hingga 87% tanpa mengurangi kinerja throughput dan end-to-end delay pada jaringan.

This work aims to evaluate Network Breathing method as an adaptive network tree construction method for ZigBee communication. ZigBee is a communication protocol for Wireless Personal Area Network (WPAN) which is built on the IEEE 802.15.4 standard. Low power characteristic of ZigBee is one of the main reasons in the selection of this protocol. An adaptive network tree construction method is designed to support this characteristic. The method is intended to form a ZigBee network topology which always minimizes the number of ZigBee routers to be active. This method will save energy consumption by turning the ZigBee routers to sleep condition when there is no end device within range to be served. The design of this method has implementation procedure such that the network topology acts like breathing, and uses Dijkstra shortest path algorithm to determine the minimum number and the position of routers to be active based on the position of the end devices. Validation to the method is carried out using the NS2 network simulator software tools, which shows reducing in router energy consumption up to 87% without degrading the throughput and end-to-end delay performance."

"In this article the nature of the religious argot associated in particular with the spirits called Andaalu Rimbu and Rundu Rimbu discussed. An attempt has been made to supply the semantic derivations for the argot terms and for alternative names of spirits, even though most of the other spirits do not have as elaborate ceremonies as the AR or RR and few others, apparently, had an argot associated with them.There are a variety of semantic processes whereby new argot terms are coined. But most of the coined names are also simply mnemonic expressions. The practical point is that without some such mnemonic device cult adherents would not be able to adapt the argot quickly.The variation in the names of the spirits suggests that the system has been in operation for a considerable time. There has also been a pragmatic approach to all cults and members are willing to borrow new rituals to supple­ ment the old. In a similar vein, it is no wonder that the Kewa of today find no problem if God is referred to by four different names by different missions in the area."
