The one-dimensional bin packing problem is defined as follows [2]. Given a finite set I = {1, . . . , n} of items and two constants c and m. Each item has a positive weight wi > 0. Is it possible to partition the set I into m subsets such that the total weight of items in each subset doesn’t exceed c? This decision problem is NP-complete in strong sense and closely related to the following sche...

Derandomized GMD can generally be summarized as follows. Each inner block zi is encoded as yi, with some weight wi representing the likelihood that the block was decoded incorrectly. For sorted wi1 < wi2 < . . . win , we erase all blocks past some threshold Θ, leaving only wi1 , wi2, . . . , wij to be decoded. We try this for all distinguishing values of Θ, that is, for all possible values of j...

The goal of this paper is to find a competitive algorithm for the following problem. We are given a hypergraph G = (X,E), |E| = n, with weighted edges and maximum edge size k. We wish to maximize the weight of a matching M ⊆ E of G, given that edges are revealed in a random order, and that when an edge e is revealed the algorithm must decide either e ∈ M or e / ∈M . Note that this is a generali...

Background: The use of devices emitted microwave radiation such as mobile phones, wireless fidelity (Wi-Fi) routers, etc. is increased rapidly. It has caused a great concern; the researchers should identify its effects on people’s health. We evaluated the protective role of Vitamin C on the metabolic and enzymatic activities of the liver after exposure to Wi-Fi routers.Material and Methods: 7...

The experts framework consists of n experts who each make predictions every day, and an online algorithm that makes a decision after seeing all the expert predictions. At the end of the day the loss/gain for each expert is revealed. The goal of the online algorithm is to perform not much worse than the single best expert over a long period of time. We analyzed the algorithm where the initial we...

In this paper, a DC-DC resonant converter with high voltage gain and small size is studied. To reduce the size and weight of this converter, the operating frequency should be as high as possible. In this research, the frequency changes from 120 to 200 kHz. Due to the high operating frequency, it is necessary to reduce the switching losses using soft switching methods. Resonant converters are su...

The three conventional anthropometric indicators of childhood undernutrition are stunting (low height-for-age), underweight (low weight-for-age) and wasting (low weight-for-height). Recently a new composite index, namely the Composite Index of Anthropometric Failure (CIAF) has been proposed and utilised to study childhood undernutrition. In this paper, we have attempted to construct three new i...

This paper proposes using a WiFi-based identification system, Wi-ID, to identify users from their unique hand gestures. Hand gestures the popular game rock-paper-scissors are utilized for system’s user authentication commands. The whole feature of three is extracted instead single gesture by existing methods. Dynamic time warping (DTW) analyze amplitude information in domain based on linear dis...
