In this paper, the power delay profile (PDP) and root mean square delay spread (RMS-DS) relationship is demonstrated to satisfy the LTE-M criteria for rectangular tunnel area at 1.8GHz. The leaky coaxial cable (LCX) was exploited as a transmitting antenna for both single-input single-output (SISO) and multi-input multiple-output (MIMO) systems. The effect of changing the received antenna (Rx) distance on the variation of received power using the Ray-Tracing Method is investigated. The reflected (NLOS) and line of sight (LOS) paths between the LCX and receiving antenna for both vertical and horizontal polarizations are deliberated and it was found that the horizontal polarized LCXs accomplish better performance than the vertically polarized cables used for both SISO and MIMO systems under tunnel environment. Furthermore, it was determined that the minimum distance between transmitting and receiving antennas can acquire higher received power.

The purpose of this study is to conduct an in-depth analysis of the existing risk management framework to explore the roles, responsibilities, and hindrances of Chief Risk Officer (CRO) to better manage the risk governance issues of commercial banking industry of Pakistan. A qualitative research design was adopted for this study to carry out an in-depth evaluation of the existing risk management framework. A case study based research strategy was adopted in which in-depth interviews were conducted from the CROs/Heads of Risk of commercial banks of Pakistan. The thematic analysis reveals that there are certain deficiencies in the existing risk management framework which are incorrect positioning of CRO, lack of maturity of risk management capabilities; weak risk culture; de-risk software solutions; advanced risk techniques and tested risk models for effective risk assessment & analysis. Furthermore, it is suggested that the Board of Directors (BoDs) design policies to create a risk culture in the bank so that every person in the bank will understand the importance of risk management that could lead to correct the positioning of CROs in the banks so that the CROs can play their part in the most effective way.

Keywords: Music therapy; Persian Music; Alzheimer's disease; Speech disorder; Short-term test of mental status (MMSE).
Alzheimer's disease and dementia had been of the most serious humanitarian crises in industrial societies over the past decades, where many elderly people are affected. However, despite the young population pyramid in Iran over the past few decades, predictions are indicative of an increase in the elderly population in the decades to come. Thus, the increase in Alzheimer's disease is a natural and inevitable event and the level of knowledge and ability of care and treatment centers for the elderly should be at an acceptable level regarding prevention and treatment. One of the recommended therapies for this disease and its disorders, especially speech disorders, is music therapy. Despite many studies concerning the effects of music therapy on patients with Alzheimer's, no studies have been done on the effect of Iranian music on Alzheimer's patients. The present paper examined the effect of this treatment on 22 elderly patients with moderate and severe Alzheimer`s disease admitted to one of the elderly care centers for 14 days. The effectiveness evaluation method was performed using the short-term test of mental status (MMSE Test) at two stages -before the start of the treatment and after the end of the second week of the treatment. The results of recording data showed the positive effect of Iranian music on the progression of the cognitive ability of the patients, and the speaking ability increased in all cases, except in one sample, well showing the effect of this type of music on the treatment and improvement of the patients with Alzheimer's and its speech-related disorders.

Keywords: Maximum Power Point Tracking (MPPT); Photovoltaic Panel; Perturb and Observe; Solar Cell; Zero Current Switching Converters.
Nowadays, increasing fossil fuel usage in communities has led to an unpleasant consequence. Environmental pollution is caused by unnecessary consumption, on the other hand, the reduction of resources are the most important consequences. Hence, using renewable and clean fuels like solar energy is a good replacement. In many countries, solar cells play a significant role in generating electricity, but the cost of electricity produced by them is very high due to the high cost of construction and maintenance; that is why they are less popular. Many efforts have been made in recent years, to determine the working point of solar cells which are used in any environment and at maximum power. The peak power point The point at which the cell has the highest output power is called, called the maximum power point tracking (MPPT) technique, in terms of how to set the point of reference at the maximum power point. In this thesis, some techniques for tracking the maximum power point of solar cells have been introduced; among them the performance of two hill-climbing techniques and incremental conductance in variable environmental conditions and two scenarios have been investigated.

Keywords: Kaczmarz algorithm; Limit polygon; Sequential projections; Affine operator; Sequence of hyperplanes; Overdetermined linear systems.
In this article, we study the properties of the algorithm for solving systems of linear equations based on the sequential projections of an initial approximation point on the hyperplanes, defined by the equations of the system (Kaczmarz algorithm). We consider the case of overdetermined systems when the sequence of approximations converges to a limit cycle, the points of which we regard as the vertices of a limit polygon. Although the proof of convergence to the limit polygon is known, we are discussing a simplified version, relating to the case of general position and clarifying the main idea of the proof. The properties of the limit polygon are little studied, but at the same time, they are important for applications. We explain that, with a proper choice of a system of equations, the limit polygon can be any predefined polygon. In other words, there are no restrictions on the type of limit polygon.

Nowadays, the bioenvironmental problems are one of the fundamental issues related to the city and are resulted from their conflict with the natural environment; because the urban development involves the predominance of buildings, industries, transformations, and economic activities on the natural spaces. With the development of cities, the landscapes and values of natural environment have been exposed to further destruction and erosion and the urban residents have been deprived of the natural attractions and the mental and social problems have appeared. Nowadays, the notion of cities without effective green spaces with its different forms is not comparable. To be able to adjust their sustainability, the cities as the focal centers of activities and human beings' living should accept the structure and function affected by the natural systems. Meanwhile, the urban green spaces as the necessary and inseparable component of the unique framework of the cities play a significant role in their metabolism that their scarcity can cause severe disorders in the life of cities. The results have revealed that the urban green spaces have social and ecologic output and the most important effect of green space on the cities is their bioenvironmental functions or ecologic output which make the cities ready for living and challenge the destroying effects of development of the transportation and improve the quality of the citizens' life. The urban green space is so important that nowadays, it is considered as one of the indexes of the development of the communities. The most important effects of the green spaces on the cities are the reduction of noise and air pollution, temperature modification, increase of relative moisture, air moderation and dust absorption. The other effects of the green space on the cities are relative, but all its effects make their presence in the cities inevitable. In this paper, it has been tried to present the definitions and explanations related to the green space and urban environment and their different functions in the city.

Soil improvements, especially performance must give attention to behaviors particularly for reinforced earth slopes is their performance against earthquakes. In this study, we attempt to perform numerical modeling studies using FLAC3D finite difference software. With the FISH programming language available in this software as well as the existing attenuation models, some arbitrary behavior and precise modeling are done. The main purpose of this study is to investigate the dynamic and nonlinear behavior of reinforced earth slope. For this purpose, an instrumented articulated roof attic that has been constructed and operated as a road embankment is used as the base model. Seismic conditions are applied to the model using the acceleration mapping of several major earthquakes of Iran and the world. The soil behavioral model has been based on a soft or hardened Mohr-Coulomb model with the capability to incorporate nonlinear behavior in static analysis with nonlinear attenuation models in dynamic analysis.
