Modelling and forecasting energy demand of Bangladesh using AI based algorithms

Bangladesh being one of the five fastest growing economies in the world with its enormous 164.7 million population is facing a huge challenge of adapting to the surging demand of electricity rising throughout the country to support its blooming economy. Load forecasting can play a vital role to overcome this challenge as it serves as an imperative tool behind electric utilities planning and operation management. Forecast loads serve as the basis of many operational decisions such ensuring maximum utilization of power by avoiding under or over generation; understanding future load demand to make economically viable investment decisions; management of resources; infrastructure development along with maintenance schedule planning. This study, first of all, proposes an automated model that fetches data from daily load generation reports (kept in pdf format) found in the Bangladesh Power Development Boards website [54] to generate a compact dataset of our historical load data with which we have conducted this research. The necessity of this model is no publicly available dataset have been found so far that contains the historical load data along with data of other important features that effect the forecast load. Secondly, we have approached three major machine learning methods – K Nearest Neighbor, Random Forest, and Long Short Term Memory (LSTM) to observe how these algorithms perform in forecasting load based on the historical electric load data of Bangladesh and what features play important roles to accurately forecast load. We have found that among these three algorithms; LSTM yields the best result having minimal prediction error compared to the other algorithms.

Neighbor-A-Posteriori Information Assisted Cell-State Adaptive Detector for NAND Flash Memory

Cell-to-Cell interferences (CCIs), which arise from adjacent cells through parasitic coupling-capacitance, severely degrade the performance of threshold voltage detection. Pre-processing and post-processing methods have been proposed to mitigate the effect of CCIs on threshold voltage variation. The performance of the aforementioned methods heavily depends on the accuracy of the threshold voltages adjacent to the victim cells. However, to obtain high accuracy, these methods requires multi-sensing operations, thus significantly resulting in high detection latency. In this letter, a novel non-uniform detection scheme based on the threshold voltage of cell states, which is referred to as the cell-state adaptive detection (CSAD), is proposed to adapt the shifts of the threshold voltages. Then, the neighbor-a-posteriori information is exploited to mitigate the overcompensation phenomenon and further improve the performance of the CSAD under the block read mode scenario. Simulation results show that the proposed CSAD scheme and its improved version not only achieve better bit-error-rate performance but also keep lower detection latency compared with the existing detection schemes.

Responding to Student Reaction to a Simple Spreadsheet Exercise in a Sociology Undergraduate Class

An individually assessed exercise used a spreadsheet as a simple organising tool to investigate refereed journal literature about communities in an undergraduate third-year sociology class. The spreadsheet exercise has proved to be a revelation in the responses of students being asked to undertake the assignment valued at fifteen per cent of total grade. This reaction to the teaching exercise has been consistent across several years the class has run, notwithstanding refinements from student feedback and other adjustments to achieve the pedagogical intention of the instructor. The article describes how the exercise challenges students to identify, list and organize the wealth of journal literature sources available in the intersecting academic fields studying communities, so they can later draw on this material in their main research assignment for the subject. Underlying assumptions of the teaching exercise include the belief that some minimal spreadsheet competence is today necessary for any professional, managerial or administrative workforce role, regardless of training domain in science, social science or humanities.
An analysis framework for building commodity futures market simulation model based on heterogeneous traders

Futures price volatility is always the hot topic for academic researchers and traders in futures market. For exploring the ru les of futures price fluctuation, we try to develop a new analysing framework from the angle of the heterogeneous traders. We describe heterogeneous traders as four respects: trading motive, predict styles, risk-return preference, reaction speed, which can accurately describe the heterogeneous traders in futures market. According to the categories of heterogeneous traders, we construct traders’ internal model, which is used in a commodity futures market simulation model to verify the framework, and the results show the framework is useful.
Review of Metamaterials , Types and Design Approaches

Metamaterials are one of the most significant and interesting theme for the Electromagnetic Field Theory in the recent past. Many scientific efforts have been performed and analyzed in this field and concluding that the metamaterials have unique and incredible properties which can be used to increase the key performances of conventional devices. Basically metamaterials are considered in the category which show different behavior under the effect of electric and magnetic field than those materials which are naturally derived. The response of the metamaterials inspired devices at the high frequencies is much better than the devices with conventional materials. Use of metamaterials in various antenna designing and fabrication enhances the gain profile, efficiency and bandwidth requirements. In this paper, we will discuss about the brief history and types of metamaterials, its structure based various properties and approaches.
interracial interactions Concerns about appearing prejudiced : Implications for anxiety during daily

We investigated the relationship between Whites’ and ethnic minorities’ concerns about appearing prejudiced and anxiety during daily interracial interactions. College roommate pairs completed an individual difference measure of concerns about appearing prejudiced at the beginning of the semester. Then they completed measures of anxiety and perceptions of their roommates’ anxietyrelated behaviors for 15 days. Results indicated that among interracial roommate pairs, Whites’ and ethnic minorities’ concerns about appearing prejudiced were related to their self-reported anxiety on a daily basis; but this was not the case among same-race roommate pairs. In addition, among interracial roommate pairs, roommates who were concerned about appearing prejudiced began to “leak” their anxiety towards the end of the diary period, as indicated by their out-group roommate who perceived their anxious behaviors as increasing across time, and who consequently liked them less. The implications of these findings for intergroup relations are discussed in this article.

DRUG CRIME AND THE URBAN MOSAIC : The locational choices of drug crime in relation to high streets , bars , schools and hospitals 101

This paper reports on initial findings from multidisciplinary research investigating the spatial and temporal distribution of illegal drug crime in one of the boroughs in London, United Kingdom. The physical location of more than 700 incidents of drug dealing were analysed at the street segment level using count regression models. The main focus was on testing the hypothesis that drug dealing is likely to happen close to facilities that inherently and routinely generate a large flow of people. To do this, the space syntax methodology of predicting movement flows in the urban environment was employed. The results showed that factors such as topological street accessibility and proximity to specific land uses have a significant effect on drug dealing locational choices.
The prevalence and associated factors of neuropathic pain symptoms in a cohort of multi-ethnic Malaysian patients with diabetes mellitus

Objective: To determine prevalence and factors associated with neuropathic pain symptoms in a multiethnic cohort of Malaysian adult diabetic patients. Methods: This was aprospective cross-sectional observational study of hospital-based diabetic outpatients in Malaysia. Subjects were interviewed for their demographic data and medical history. The painDETECT questionnaire was used to screen for neuropathic pain symptoms and pain intensity was assessed using the numeric pain rating scale (NPRS). Neuropathy symptoms and signs were assessed using the Neuropathy Symptom Score (NSS) and Neuropathy Disability Score (NDS). Results:Of 242 patients,140 (58%) were women, with a mean age of 61 + 11.4 years (range 21 to 81). Ninety nine(40.9%) were Malay, 64 (26.4%) Chinese, 76 (31.4%) Indian and three (1.2%) were Eurasian. Mean duration of diabetes was 15.9+ 9.8 years (range 1 to 53) and 232 (95.9%) patients had Type II diabetes. Peripheral neuropathy,based on NSS and NDS criteria, was found in 83 (34.3%). Thirteen (5.4%) patients were found to likely have neuropathic pain symptoms and this was independently associated with peripheral neuropathy ((OR) = 3.40, 95% confidence interval (CI): 1.04, 11.14) and Indian ethnicity (OR = 5.44, 95% CI: 1.50, 19.57)). Patients with neuropathic pain had higher average pain intensity scores. Conclusions: The prevalence of neuropathic pain symptoms in a Malaysian DM patient cohort was low and was associated with the severity of neuropathy symptoms and Indian ethnicity. The causes for ethnic differences are unknown and could be due socio-cultural or physiological differences in neuropathic pain perception.
Achieving Qualities During the Development of LOTOS Specifications

The LOTOS language is useful for the specification of services and communication protocols. Main recognised qualities of such specifications are simplicity, readability, provability, modularity (extensionability, rearrangeability) or composability. In this paper, we identify and formalise some of the qualities which arise ``during'' the development of LOTOS specifications. Some other qualities cannot be formally defined and must be obtained by specific methods. Formalised qualities can be achieved through development operators which consist of mechanisms that operate on intermediate states of a development.

THE EFFECT OF NON-UNIFORM FRONT CONTACT RESISTANCE ON PERC SOLAR CELL PERFORMANCE

In this report, we present the simulation of 20.43 % efficiency solar cell using Griddler 2.5 Pro. The cell has a passivated emitter and rear cell (PERC) structure. It is a square p-type with local Al-BSF and screen-printed metallization. We have made strip contacts 68 μm wide and 1.4 mm pitch for full area Almetallization on the rear side of the PERC cell. We have optimized the number of front and rear fingers for the PERC structure. The front contact resistance was also optimized to study the power losses, fill factor losses, recombination currents and saturation current densities at open circuit. We have studied the effect of wrap around (0-25 mm) for the front contact resistance on the output of the Silicon PERC solar cell. It was observed that increase in the wrap around extent from 0 mm to 25 mm had affected the fill factor and efficiency of PERC solar solar cell significantly. The wrap around extent for non-uniformity in front contact resistance showed that the fill factor of PERC solar cell was decreased from 77.87 % to a value of 73.45 %. Whereas the efficiency was decreased from 20.41 % to a value of 19.26 %.

We present an analytical upper bound on the number of required vehicles for vehicle routing problems with split deliveries and any number of capacitated depots. We show that a fleet size greater than the proposed bound is not achievable based on a set of common assumptions. This property of the upper bound is proved through a dynamic programming approach. We also discuss the validity of the bound for a wide variety of routing problems with or without split deliveries. Keywords— Split delivery; Number of vehicles; Multiple depots; Dynamic programming
Discriminative feature selection for visual tracking

Visual tracking is an important role in computer vision tasks. The robustness of tracking algorithm is a challenge. Especially in complex scenarios such as clutter background, illumination variation and appearance changes etc. As an important component in tracking algorithm, the appropriateness of feature is closed related to the tracking precision. In this paper, an online discriminative feature selection is proposed to provide the tracker the most discriminative feature. Firstly, a feature pool which contains different information of the image such as gradient, gray value and edge is built. And when every frame is processed during tracking, all of these features will be extracted. Secondly, these features are ranked depend on their discrimination between target and background and the highest scored feature is chosen to represent the candidate image patch. Then, after obtaining the tracking result, the target model will be update to adapt the appearance variation. The experiment show that our method is robust when compared with other state-of-the-art algorithms.
Automatic definition of hazard-compatible accelerograms at non-rocky sites

Nonlinear dynamic analyses require accelerograms as eismic input, possibly accounting for site effect s. The rigorous approach consists in selecting real accele rograms recorded at rocky sites and propagating the m t rough the soil profile to account for local site effects. Ground response analyses require a detailed geotec hnical characterization of the site which might be unavail able. This paper presents a simplified, yet theoret ically-based procedure to propagate real accelerograms recorded at rocky sites through 1D soil profiles, for which only the value of VS,30 is required. A Monte Carlo simulation procedure is used to create a population of soil profiles compatible with VS,30. Real accelerograms recorded at rocky sites are pr opagated using the concept of transfer function through each soil profile. The mean respon e spectrum computed accounting for site effects is then used for selecting spectrum-compatible time histories us ing the signals calculated by the described procedu re which only require VS,30 and not a detailed geotechnical characterisation o f the site.

This study revealed that majority of the teachers 90(47%) had high to very high turnover intention. This study recommended that TSC, school managers and other stakeholders in the education sector should seek to make the teaching profession attractive to improve the job satisfaction and retention of teachers.
SUPERLUBRICITY BETWEEN SAPPHIRE AND PTFE ACHIEVED BY ACID

1.INTRODUCTION In the physical researches, friction phenomenon that describes the force existing between relative moving surfaces paves a great challenge to the industrial production and the energy efficiency. The friction reduction or elimination in the moving mechanical system would be extremely favorable to the industrial manufacture and the sustainable development of the earth. Therefore, the phenomenon “superlubricity” [1] that refers to friction coefficient less than 0.01 has become an appealing focus in recent years. Superlubricity has been attained both between solid interfaces and across liquid medium. The carbon based materials and two-dimensional materials, such as Molybdenum disulfide [2] and diamond like carbon film (DLC) [3] have been investigated mostly to achieve solid superlubricity. Different from the mechanism of solid superlubricity, the liquid superlubricity was mainly focused on the reduction of shear strength of confined liquid between two friction surfaces. On micro-level, Raviv et al. obtained a super-low friction of alkali salt solutions between mica surfaces by surface force apparatus (SFA) [4]. The liquid superlubricity above was mainly attributed to the hydration effect, leading to the great reduction of energy dissipation in the hydration layer [5]. At macro-scale, there are also some materials found having liquid superlubricity properties. Kato found that superlubricity can be achieved when water was confined between ceramics, where the formation of silica gel provided an efficient boundary lubrication [6]. Recently phosphoric acid solution was found to achieve superlubricity with a friction coefficient of 0.004 [7]. Compared with the solid superlubricity, the water-based superlubricity is more promising for industrial application, because of its nonsensitive to environment conditions. It is interesting and feasible to explore the water-based liquid superlubricity based on other mechanisms. In the present work, we investigated the friction properties of acid solution and a super-low friction coefficient of 0.004 was achieved between polytetrafluoroethylene (PTFE) and sapphire without a running-in process. Here the friction properties were explored with different sliding velocity and pH value of the lubricant, and a further investigation on the mechanism through which superlubricity is obtained has been performed.
P o S ( L A T T I C E 2 0 0 7 ) 1 2 0 Chiral Limit and Light Quark Masses in 2 + 1 Flavor Domain Wall QCD RBC and UKQCD Collaborations

We present results for meson masses and decay constants meas ured on 243 × 64 lattices using the domain wall fermion formulation with an extension of the fifth dimension ofLs = 16 for Nf = 2+1 dynamical quark flavors. The lightest dynamical meson mass in our set-up is around 331MeV, while partially quenched mesons reach masses as low as 250MeV. The applicability of SU(3)×SU(3) and SU(2)×SU(2) (partially quenched) chiral perturbation theory will be compared and we quote values for the low-energy constants fr om both approaches. We will extract the average light quark and strange quark masses and us e a non-perturbative renormalization technique (RI/MOM) to quote their physical values. The pion and kaon decay constants are determined at those values from our chiral fits and their ratio is us ed to obtain the CKM-matrix element |Vus|. The results presented here include statistical errors onl y.
Effect of Centella asiatica powder and mangosteen peel powder using in vitro gas production technique

The objective of this study was to determine the effect of Centella asiatica powder (CAP) and mangosteen peel powder (MPP) supplementation using in vitro gas production technique. The experimental design was a 3×3 factorial arrangement in a Completely randomized design (CRD). Factor A was 3 levels of Centella asiatica powder (CAP) (0, 5, 10 mg) and factor B was 3 levels of mangosteen peel powder (MPP) (0, 5, 10 mg). The dietary treatments were analyzed for in vitro ruminal gas production, in vitro degradability and ammonia nitrogen. It was found that supplementation of CAP and MPP affected on gas production for the insoluble fraction (b), gas production rate (c) and potential extent of gas production (a+b) (P<0.05), but did not affect on gas production from the immediately soluble fraction (a) (P>0.05). Cumulative gas production (96 h) was higher by different level of supplementation (P<0.05) and were found different in CAP 5 mg with 5 mg of MPP than in other level. However, in vitro degradability both IVDMD was significantly higher in supplementation of CAP at 5 mg with 5 mg of MPP (P<0.01) when compared with other treatments , while IVOMD was not significantly different among treatment (P>0.05). NH3-N was higher in CAP 10 mg with 5 mg of MPP. It cloud be suggests that the level of CAP supplementation at 5 mg with 5 mg of MPP increased gas production and other fermentation parameters. However, further work in in vivo trials using CAP and MPP should be conducted.
