Recently, augmented Reality (AR) is growing rapidly and much attention has been focused on interaction techniques between users and virtual objects, such as the user directly manipulating virtual objects with his/her bare hands. Therefore, the authors believe that more accurate overlay techniques will be required to interact more seamlessly. On the other hand, in AR technology, since the 3-dimensional (3D) model is superimposed on the image of the real space afterwards, it is always displayed on the front side than the hand. Thus, it becomes an unnatural scene in some cases (occlusion problem). In this study, this system considers the object-context relations between the user's hand and the virtual object by acquiring depth information of the user's finger using a depth sensor. In addition, the system defines the color range of the user's hand by performing principal component analysis (PCA) on the color information near the finger position obtained from the depth sensor and setting a threshold. Then, this system extracts an area of the hand by using the definition of the color range of the user's hand. Furthermore, the fingers are distinguished by using the Canny method. In this way, this system realizes hidden surface removal along the area of the user's hand. In the evaluation experiment, it is confirmed that the hidden surface removal in this study make it possible to distinguish between finger boundaries and to clarify and process finger contours.

In the last few years, internet traffic increases continuously due to the more use of live streaming and social sites. To accommodate such high traffic demand the more bandwidth is required. The elastic optical network (EON) is a promising solution for the capacity expansion that can meet the future bandwidth requirement. The EON can provide a higher bit rate. In this paper we purposed a recovery strategy for failure in EON. Our purposed strategy shows the more acceptance rate for randomly generated source (s)-destination (d) requests. Here we considered two topologies viz. COST239 and NSFNET. Then evaluate their performance for Recovery Time, bandwidth blocking probability (BBP) and network capacity utilization (NCU), in which our purposed scheme provides lesser BBP and lower NCU for both topologies and low recovery time than shared path protection (SPP and dedicated path protection (DPP).

Daylighting is required to enhance visual comfort; whereas its illumination provides renewable functional interior lighting for specific programmes. Hence, this study examines the levels of daylight illumination for teaching and learning in two lecture theatres each located at the Federal University of Agriculture Makurdi (UAM) and Benue State University Makurdi (BSU) in Makurdi, Nigeria. The two buildings selected for the daylighting performance employed post-occupancy evaluation approach. A digital camera was employed to take photographs, whereas digital light meters were employed to evaluate the levels of illumination on the work plane. The results showed that 80% of the study space has inadequate indoor daylight illumination quantity and distribution as well as poor daylight ratios of 1.1and 0.9 for UAM lecture theatre and BSU lecture theatre, respectively Hence, the lighting conditions in the selected buildings fall short of the international lighting benchmarks (IESNA). Therefore, a pragmatic daylight design strategy is required to enhance daylight levels in the lecture theatres for energy-saving and visual comfort as well as onwards design and fusion in the national building code.

Satellite Images (SI) play a vital role in various civilian and military applications for weather forecasting, monitoring of resources of the earth, environmental studies, observing natural disasters and natural calamities, etc. When these SI are used in military applications and almost all other applications for efficient study, the big challenge is its resolution. In wavelet transforms based satellite image enhancement techniques, choosing a proper wavelet transform plays a key role and vary with the image to image. To improve the resolution, a novel robust optimized wavelet decomposition and a bicubic interpolation-based satellite image enhancement method is proposed. In this method, the Stochastic Diffusion Search (SDS) algorithm is used to get the optimized wavelet decomposition of the image into different subbands and bicubic interpolation is used to improve the resolution. Image is decomposed using the optimized wavelet filter bank based on the SDS algorithm, decomposed sub-bands are interpolated with bicubic interpolation and inverse wavelet transform is applied to compose the interpolated sub-bands into a high-resolution image. The proposed method is tested on satellite images and other images also. Compared to the proposed method with the existing methods and proved that the proposed method is superior to existing methods and applicable to any type of image.

In recent days diabetes is recorded as fastest growingst common disease among several diseases in the world. It became one of the major health problems in several states and countries. This occurs mainly when the normal human body is incapable to produce the sufficient amount of insulin in order to adjust the quantity of sugar levels in the body. This improper maintenance of sugar levels may lead to other diseases like heart disease, kidney disease, blindness, nerve damage and blood vessels damage. every one knows that there are mainly two general reasons for diabetes: One reason is the pancreatic gland not able make sufficient insulin or the body not produce make enough insulin. This type of symptom is mainly found on 5-10 % of citizens with diabetes and they come under Type-1 Diabetes. Another reason is cells do not respond to the insulin that is produced and this type of symptom people come under Type-2 Diabetes. In recent days, machine learning as well as DM techniques have been considered to design automatic diagnosis system for diabetes. In this proposed paper we aim to use the SVM, a ML method as a classifier for identification of diabetes data set. Here we applied the data cleaning techniques to handle the incomplete by fill in absent values, smoothening the noisy data, identified and removed the inconsistencies. By performing the data cleaning activities for verifying all the fields in the data set are properly arranged or not. Once after the data cleaning is completed then we try to apply SVM and Naive Bayes for classifying the diabetes dataset and we try to compare the both classifiers and find which classification techniques are efficient by comparing the both classifiers based on the results we observed. Our experimental results clearly tell that SVM can be effectively used for identifying diabetes disease. In this proposed application we try to analyze the diabetes based on location wise i.e. diabetes is differently affected by various people in and around the various corners of the city. In this proposed application we take sample data set of Visakhapatnam city with four area’s data like NORTH, SOUTH, and WEST & EAST. So by applying the SVM, we will try to analyze the different reasons which differ for each and every diabetes patients based on location wise. some area people mostly suffer with food, pollution, eating habits, daily habits, sleeping habits and other reasons. So based on each and every individual region diabetes differ one with other person in and around the city. So we are going to classify a set of patients data based on region wise and classify the cause of affecting diabetes for them and try to provide a counter measure and pre-cautions for the patients.

Earthquakes are the natural disaster occurring since years but during the last two decades they are causing huge looses whether it may economic or to life. This paper focuses to evaluate the seismic performance of various building confirming to Indian standard criteria for earthquake resistant design of structures and ductile detailing of reinforced concrete structures subjected to seismic Forces-code of practice, Bureau of Indian Standards, both as per the revised codes in the year 2016. Due to ground shaking, seismic loads are the governing load and thus it becomes necessary to assess the conditional probability of structural response. Use of HAZUS methodology is followed to construct seismic fragility curves as it is well-organized and defined approach. Spectral displacement plays the functional parameter to derive the expected damage for fragility. This work represented here is compiled by means of procedure for establishing the fragility curves for three typical Reinforced Concrete (RC) frame structures having variations resembling 3 storey intended for short-period structures, 6 storey used for medium-period structures and 12 storey representing long-period structures using SAP2000 as a software tool for analyzing the structure. Furthermore an attempt is made for focus on the variation of one of the major structural configuration i.e. slab thickness which is not certainly paid attention as compared to columns and beams. Slabs adds additional stiffness to the structure which can enlighten how it behaviour would be when subjected to ground excitation. As a result, the fragility curves are plotted to study the impact due to slab thickness in order they are carefully selected while design.

The traffic volume due to bandwidth hungry multimedia and internet applications is growing exponentially and demands a significant change in communication networks. Due to the high speed communication requirements present researchers are giving interest in efficient, adaptive and cost effective optical network design. Recent works in optical networking using optical fiber communication focusing on the efficient utilization of resources by flexibly utilizing the spectrum and adaptive networking to support a better quality of service (QoS). The flexible grid in optical spectrum and adaptive optical networking save spectrum with improvement in energy and spectral efficiency. Simple modulation of a signal can support lower bit rate transmissions, which are more sophisticated for higher bit rates. Recent advances on hardware such as optical transponders and switches make it more feasible to develop a new elastic-optical networking (EON) paradigm. Current research efforts are on new innovations of optical transponders and optical switches to support EON functionalities. The measure of spectrum utilization factor with respect to the value of traffic requirement increases the flexibility of the networks. The Integer Linear Programming (ILP) is used to extract the optimal solution for analysis of utilized frequency slots with available slots and increased traffic in the network. This framework also calculates the spectrum utilization for different traffic in order to choose required frequency slot for the EON to provide uninterrupted network service.

Future Underwater communication demands high speed data transmission. Present Underwater communication can only provide a limited data rate, where the available bandwidth is limited. To increase the data rate, we simulate the MIMO-OFDM with IDMA technique. In MIMO method many transmitter and many receiver antennas are present. MIMO method offer a very high capacity which raises linearly with the numeral of antennas. Data rate increases with MIMO method, bandwidth is saved and fading is reduced with OFDM. In OFDM technique the complete sign orthogonally overlays in a frequency field that secures the bandwidth. IDMA system is constructed on interleaving procedure. In this paper different coding techniques Convolutional, RS code, LDPC code, Turbo code with IDMA OFDM MIMO technique are compared. IDMA OFDM MIMO with Turbo code, BER performance is improved up to 10-6.

The requirement of the modern application is to transmit wide bandwidth of signal with the low latency. The optical fibers provide wide transmission bandwidth along with very little delay as well as choice on choosing transmission medium for high data rate. However, Stimulated Brillouin Scattering (SBS) is a nonlinear optical effect that restricts power level into a fiber to few milliwatts. It degrades the Q-factor and consequently the bit error rate of an optical fiber link. For suppression of SBS, various approaches have been used previously such as PSK, ASK, FSK, CSRZ-DQPSK etc. Among all the previous techniques, CSRZ-DQPSK transmitter is considered as the most efficient one for suppression of SBS. However, it consists of some drawbacks such as low spectrum efficiency, susceptibility to phase variation and short communication range, due to which requirement arises of upgrading the previous work. Therefore, in the proposed work (i.e. CSRZ-DP-QPSK), DP-QPSK scheme is used which makes the system more efficient as it has high spectrum efficiency and improved sensitivity. Also, the communication range is elongated in present work. The performance evaluation of CSRZ-DP-QPSK approach has been performed in terms of Q-Factor, BER, and threshold. Also, the comparative analysis of the proposed approach with conventional approaches has been performed and from the obtained results it has been demonstrated that proposed work is more efficient than conventional one as it has better SBS tolerance and improved BER.

Parking space is becoming a serious problem due to increasing number of vehicles along with the mismanagement of available parking space. Particularly, in places where sports or artistic events are scheduled, searching for parking space is a major problem. In order to combat this problem, Smart Parking Platform is implemented using sensors to detect when a car enters or leaves a parking lot in order to track capacity and alert drivers about availability of parking space. Inefficient management of parking system effects traffic flow and also leads to wastage of time and fuel. Smart Parking Platform smoothens the parking experience and achieves convenience for users by displaying the status of the parking slots in web browser and guiding drivers towards empty parking slot. In this paper, each parking slot is equipped with an ultrasonic sensor which is interfaced to Arduino UNO microcontroller. Arduino UNO sends the trigger pulse to the ultrasonic sensor. Ultrasonic sensors senses whether the parking slot is empty or occupied and sends the data from echo pin to Arduino UNO, which is programmed in such a way that it processes the data and communicates to Node MCU. The status of the parking spaces is updated in the webpage regularly. The user can access the information regarding parking slots by connecting to the provided network. If a parking slot is empty, it is represented by green block. If it is filled, it is represented by red block. This project aims towards reducing traffic congestion and time while searching for parking space. It can be applicable in places such as convention centers, shopping malls, airports, bus stations, stadiums and theatres.

Architectural trends and their developments witnessed new ideas at many levels; one of these ideas is known as consumption, which is one of the new themes in an old concept and in its presence, which takes place effective today in the field of architecture. And plays a role in changing the architectural constants targets, and plays a role in changing the architectural constants targets, or classification of priorities. Every body tries to search for new and evolving architecture through what is available has advanced technological methods. This will be directed Search, make the process of change and evolution in architecture is not only very close and meet human needs, but to make the first need produce innovative and creative architecture. Determine the general direction of search in the consumption of meaning forms in architecture The research theoretical knowledge for consumption in architecture, as Figure concept of evolution, and the need to study technology and its relationship with both local architecture and globalization. And a global review of various studies to try to reach the first step of the research problem of (knowledge before about formats consumption in meaning and form in the context of local architecture). And thus produced the aim of the research, to clarify the concept of consumption in architecture, through, to clarify the presence of consumption in the local architecture, and the potential to achieve consumption in the local architecture. Knowledge has helped to enrich the architectural framework of research and the formation of his variable, enhanced architectural studies available to achieve a theoretical framework integrated, variable has been to, the consumption component, and intellectual attitudes towards consumption, and forms adopted, and detailed processes. To use variable, has helped in the application on projects elected, so as to achieve a comprehensive conception of the nature of the relationship between variables, when applied collectively elected on samples of the application. The research found that consumption is a copy of the forms, and unconsumption is a simulation and new styles of architecture and context beyond.

"Virtual reality technology is the most important techniques reached by the technological revolution in the last decades of the twentieth century. It had a significant impact in various fields of life, especially in the field of architecture through the presentation and realizing the product of architecture, The improve in technology and virtual reality techniques, including CAVE systemwas depend on how to understand the third dimension of space and sense of it. So it was necessary to keep pace with this development locally in Iraq and try to show its impact onthis evolution in the perception of space and the sense of being part of it. From here the research problem identified as: (the impact of the cave system techniques in the perception of space at the local level). The aim of this research was to show the improvement in receiver perception when the technological developments taking place in the world of virtual reality.To achieve this aim the research follows these steps:• Develop a comprehensive theoretical framework by presentation the most important factors affected in the receiver perception and the properties of perceived characteristics of space to identify the most important items that affect the process of cognition and the characteristics of the cognitive space perceived.• Creating a local virtual environment experience using a cave system technology, and applied to an architectural project designed by the researcher in the Department of Architecture - University of Technology.• Measure the level of awareness of the recipient when using the cave system technology that have been created in this research by comparing with the normal computer screen technology.The research reach a number of conclusions showing improvement in the performance of technical CAVE system in the perception of space compared to traditional techniques the computer screen."

التبئير كأستراتيجية انتاج وقراءة للنص المعماري المعاصر
Authors: Hamza Abass Ali
Published: February 2020

تعتبر  العملية التصميمية المعاصرة هي عملية عقلية  تتسم بالمرونة والابداع  بهدف تكوين نصوص معمارية تسعى للتواصل مع المتلقي . ولتحقيق هذا التواصل  افرزت الدراسات عدد من الاستراتيجيات التي يمكن نقلها واعتمادها في حقل العمارة  كأساليب يعتمدها المصمم في ايصال الدلالات المحملة برسائل عن طريق تشكيل تلك النصوص كدوال معمارية تتسم بالبلاغة والابداع ، ومن ضمن هذه الاستراتيجيات التبئير والمعتمدة في الحقل الادبي وخصوصا القصصي في جانب  السرد منه  , وبحكم انفتاح العمارة على الحقول المعرفية الاخرى , ارتأى البحث نقل هذه الستراتيجية المهمة الى العمارة كألية تواصل في نقل الاحداث وتضمين الدلالات بصيغ جديده من خلال وصف الظواهر عن طريق تجسيد رؤية المصمم لها . وعليه تكونت المشكلة البحثية بـ " وجود قصور معرفي حول التبئير كاستراتيجية تصميم وقراءة في حقل العمارة المعاصرة  " . واعتمد البحث الفرضية التالية بأن النصوص المعمارية هي احدى الصيغ السردية ذات الدلالات المبئرة في نقل حدث او وصف ظاهرة مجتمعية ما " .
