In the paper we describe the applicability of different types of resources and activity modules in the e-learning courses and the worthiness of their usage. The presented ideas are supported by the outcomes of the questionnaire research realized within the elearning study as well as the usage analysis of particular e-course ―Role of a nurse in community care‖ which was one of the outcomes of th...

Efficient nutrient usage is a trait under universal selection. A substantial part of cellular resources is spent on making nucleotides. We thus expect preferential use of cheaper nucleotides especially in transcribed sequences, which are often amplified thousand-fold compared with genomic sequences. To test this hypothesis, we derive a mutation-selection-drift equilibrium model for nucleotide s...

Household electrical energy consumption represents a major chunk of the total demand. This demand is also exhibiting steady increase whereas supplies are struggling to keep up. This poses two key challenges to Demand-Side Management (DSM) – achieving unrealized energy savings and, reducing peak loads. Energy saving in households has not yet achieved its potential chiefly because of poor feedbac...

Reducing the energy consumption of PCs is becoming increasingly important with rising energy costs and environmental concerns. Sleep states such as S3 (suspend to RAM) save energy, but are often not appropriate because ongoing networking tasks, such as accepting remote desktop logins or performing background file transfers, must be supported. In this paper we present Somniloquy, an architecture...

The past years have witnessed a significant increase in the number of WLANs deployed in most of the enterprises, campuses and public areas to provide high-speed Internet connectivity. These WLANs typically consist of APs densely installed to assure enough capacity to meet users demand during the peak period of activity. At the same time, it translates into a serious energy wastage during low-ut...

Indonesia is a tropical country located on the equator. The average intensity of solar radiation in 4.8 kWh/m2. This makes with new and ren ewable energy potential, one which panel technology. first step that must be done process installing panels place to analyze potential energy. In this study, an analysis as renewable source has been carried out at Budi Luhur University, North Petukangan, So...

Advancements in computing and communication technologies have given rise to low-cost embedded devices with applications in diverse domains such as Smarthome, industrial automation, healthcare, transportation etc. These devices are power-constrained which emphasizes the need for lightweight security solutions. Code obfuscation has been demonstrated to provide time-limited protection of source co...

Applying dynamic voltage scaling technique to design a low-power register file plays an important role in modern embedded-processor design. In this paper, we propose a compiler-aided approach to find out in a program which and when the registers would not be used, and to turn these unused registers into low power mode through voltagescaling controls. The proposed approach can be partitioned int...

Energy consumption as an increasingly important decision criterion has to be included in the search for good architectural and design alternatives to make an embedded system as energy-efficient as possible. The proposed method describes a system with dedicated extended UML models for applications and hardware components and evaluates the energy use via a transformation into an analyzable stocha...
