This document discusses the idea of constructing multi-functional storage reservoirs in mountain regions of Poland. Small reservoirs could be built instead of large ones by taking advantage of the terrain and using naturally occurring rock eluvium to form cofferdams. This would help address issues like floods, droughts, and uneven water distribution. The flysch rock formations and eluvium soils in mountainous areas of southern Poland are well-suited for small reservoir construction without needing additional sealing due to their composition and properties. Such reservoirs could provide benefits like increased water resources, flood protection, landscape preservation, and slope stabilization.

In recent years many websites have started providing keyword search services on maps. In
these systems, users may experience difficulties finding the entities they are looking for if they do not
know their exact spelling, such as a name of a restaurant. In this paper, we present a novel index
structure and corresponding search algorithm for answering map based approximate-keyword in an
Euclidean space so that the users get their desired results even though they have typos in the keyword.
This work mainly focuses on investigating range queries in Euclidean space

The document discusses the benefits of exercise for mental health. Regular physical activity can help reduce anxiety and depression and improve mood and cognitive functioning. Exercise causes chemical changes in the brain that may help protect against mental illness and improve symptoms.
This document summarizes research on a series of siloxane-based side chain liquid crystal polymers where the length of the coupling chain between the mesogenic unit and polymer backbone was systematically varied. All polymers exhibited a smectic phase and the nematic-isotropic transition temperature increased with longer coupling chain length. Electro-optic measurements found that threshold voltage for reorientation decreased with increasing chain length due to changes in intrinsic curvature elasticity rather than orientational order. A model is presented where constraints from coupling the mesogenic units to the backbone influence the observed electric-optic properties as chain length varies.
This document provides a survey of iris segmentation algorithms that have been developed. It discusses the importance of accurate iris segmentation to the effectiveness of iris recognition systems. The major existing iris segmentation techniques are Daugman's integro-differential operator method and Wildes' Hough transform-based approach. The document reviews several iris segmentation algorithms from literature and identifies some limitations, including that much work still needs to be done on segmenting black irises accurately.

Tracking Of Multiple Auvs in Two Dimensional PlaneIJMER
This document discusses tracking of multiple autonomous underwater vehicles (AUVs) in a two-dimensional plane using a leader-follower approach. It describes modeling AUV motion using 6 degrees of freedom involving linear and angular position, velocity, and forces. The document outlines AUV kinematics involving modeling motion between an inertial and body fixed frame. It also discusses AUV dynamics and developing a mathematical model accounting for rigid body properties and added mass effects. Finally, it proposes using a proportional derivative controller to track a reference circular path and generate control signals to reduce position error, allowing an AUV to follow a leader's trajectory.
Electric Load Forecasting Using Genetic Algorithm – A Review IJMER
Many real-world problems from operations research and management science are very
complex in nature and quite hard to solve by conventional optimization techniques. So, intelligent
solutions based on genetic algorithm (GA), to solve these complicated practical problems in various
sectors are becoming more and more widespread nowadays. GAs are being developed and deployed
worldwide in myriad applications, mainly because of their symbolic reasoning, flexibility and
explanation capabilities.
This paper provides an overview of GAs, as well as their current use in the field of electric load
forecasting. The types of GA are outlined, leading to a discussion of the various types and parameters of
load forecasting. The paper concludes by sharing thoughts and estimations on GA for load forecasting
for future prospects in this area. This review reveals that although still regarded as a novel
methodology, GA technologies are shown to have matured to the point of offering real practical benefits
in many of their applications.
Methodology used for improving overall equipment effectiveness by Implementi...IJMER
The global marketplace is highly competitive and organizations who want to survive long-term, have to continuously improve, change and adapt in response to market demands. Improvements in
a company's performance should focus on cost cutting, increasing productivity levels, quality and
guaranteeing deliveries in order to satisfy customers. Total Productive Maintenance (TPM) is one
method, which can be used to achieve these goals. TPM is an approach to equipment management that
involves employees from both production and maintenance departments. Its purpose is to eliminate major
production losses by introducing a program of continuous and systematic improvements to production
equipment.
This document discusses research into optimizing ozone production in a coaxial wire-cylinder reactor. It presents the experimental setup, which uses a glass tube reactor with inner and outer electrodes. Experiments varied the applied voltage, gas flow rate, gap between electrodes, and electrode area. The main findings were that ozone concentration increased with voltage and electrode area, and decreased with flow rate and gap size. When using dry air compared to pure oxygen, ozone levels were lower due to the lower oxygen concentration in air. Overall, the research aimed to better understand how design parameters impact ozone generation in this reactor type.

This document summarizes a research paper that proposes global block-based redundancy architectures for self-repairing of embedded memories. The key points are:
- Redundant rows and columns of memory are divided into blocks that can replace faulty blocks anywhere in the memory array, rather than just within the same row or column. This global approach helps repair clustered faults.
- A modified essential spare pivoting (MESP) algorithm is proposed for built-in redundancy analysis that has low area overhead. It collects faulty cell information and analyzes block-level faults.
- Simulation results show the proposed architectures and MESP algorithm significantly improve manufacturing yield, repair rates, and reliability compared to other approaches, due to their efficient
This document summarizes a study that proposes new calibration estimators for estimating population means using stratified random sampling. Specifically, it defines calibration estimators that minimize different distance measures between the original design weights and new calibration weights. Through simulation, the estimators are compared based on their empirical mean squared error. The simulation results show that the calibration estimator using distance measure L1 is more efficient than the one using distance measure L3. In general, the document presents theoretical derivations of calibration estimators under different distance measures and evaluates their performance through a simulation study.

DC Motor Fed with Double Input Z-Source DC-DC ConverterIJMER
The document presents a double input Z-source DC-DC converter to power a DC motor. Some key points:
- The converter allows two DC voltage sources to power the load individually or simultaneously for applications using multiple energy sources.
- It consists of two DC sources, four diodes, split inductors and capacitors in a 'Z-network', and a switch. There are four operating states based on the active/inactive states of the two sources.
- In state 1, both sources are active so the input voltage is the sum of the two voltages. In states 2 and 3, one source is active while the other is inactive. In state 4, both sources are inactive.

The document summarizes a research paper on using particle swarm optimization to minimize power losses in a permanent magnet synchronous generator for wind turbines. It begins with an introduction to the challenges of renewable energy and why permanent magnet synchronous generators are commonly used for wind power generation. It then provides a high-level overview of the proposed method which uses PSO to optimize the d-axis stator current control of the generator to minimize copper and core losses. The document concludes by briefly outlining the modeling approaches for the wind turbine system and permanent magnet synchronous generator that are used in the research.
