Document retrieval is the process of matching of some sated user query against a set of free-text records (documents), its one major technique for organizing and managing information. This project was concerned with studying which of the different statistical measures in IR have the most effectiveness on document retrieval using a unified set of documents. The results show that the Cosine Simil...

Many organizations in the world are seeking effective means to provide financial assistance brilliant but needy students. research works have been conducted determine students based on classification methods which fail separate financially stable from ones as class labels for affected by manual reviews, randomness and discretion of selection committee. This paper presents a hybrid clustering me...

This paper presents a method for fast planning within arbitrary maps, through segmentation of the map into Manhattan-cohesive areas. A Manhattan-cohesive area is a connected part of the map where the optimal distance between any two points in the area is equal to their Manhattan distance. We adopt a four directions Manhattan distance, where diagonal moves are allowed. In the paper we present th...

Environmental health is an important aspect in efforts to achieve public health. The condition of environmental Indonesia varies each province, so the priorities for increasing are also different. This study aims grouping provinces based on indicators order know high/low quality province assist government optimizing efforts. done partitioning around medoids method which robust data containing o...

High-dimensional vectors are ubiquitous in algorithms and this lecture seeks to introduce some common properties of these vectors. We encounter the so-called curse of dimensionality which refers to the fact that algorithms are simply harder to design in high dimensions and often have a running time exponential in the dimension. We also show that it is possible to reduce the dimension of a datas...

In the research field, network performance for different smart applications plays an important role in IoT network. Several factors, such as packet delay, throughput, energy consumption, heterogeneity, proper gateway placement and load balancing, have a greater impact on performance. this article, two optimal are investigated order to improve of Various methods used find lo-cation Coordinating ...

Assume n wireless mobile sensors are initially dispersed in an ad hoc manner in a rectangular region. They are required to move to final locations so that they can detect any intruder crossing the region in a direction parallel to the sides of the rectangle, and thus provide weak barrier coverage of the region. We study three optimization problems related to the movement of sensors to achieve w...
