Interactive grammar based design systems (IGBDS) are capable of generating large numbers of alternative designs. Prior to the application of IGBDS, a set of rules should be defined based on the theoretical theories and practical experiences in designing the objects, or by analysing the existing sets of objects. However, due to the time constraints in developing theoretical theories, gaining the practical skills of experts is of qualitative in nature and stylistically inconsistent designs to be analysed, it is difficult to systematically derive a set of shape grammar rules in generating designs which fulfils specific requirements. To address this problem, this paper presents an IGBDS enhanced by evolutionary computing to evolve a set of grammar rules for product form design. In this research, the forms of a product are analysed to derive shape features in the form of shape grammar (SG) rules. the rules are then encoded as the code scripts of a genetic algorithm (GA) representation in order to generate new shape grammar rules. the parameters in GA representation are modified by genetic programming (GP) which is regulated by control planning strategies named "GP-GA-SG". the "GP-GA-SG" control planning strategy first defines ways on how the control variables in GP should modify the variables in GA representation. the "GP-GA-SG" control planning strategy then defines ways on how the control variables in GA should modify the variables in SG representation. the SG rules modified by the GA variables define a new combination of shape features for alternative designs. In this way, traditional shape grammar is extended to an interactive context in which generative and evolutionary computing methods are combined. Both product component design as well as product configuration are supported in this framework. In this paper, we describe how this framework is formulated and discuss its potentials in supporting product design, with initial examples showing how the system is intended

the most significant issue in cities is garbage collection. the average amount of waste a person produces daily rises as the population grows, creating severe waste management issues. Any municipality's most pressing issues are bin status monitoring, locating the shortest route, and vehicle costs. the problem's consequences result in inadequate waste monitoring and management procedures. An effective garbage collection system that periodically measures the amount of garbage in the bins is used to solve these issues. the shortest route can be determined using this bin's status. the vehicle only went to the places where the bins in the city are full. the Wi-Fi module will transmit all of the information to the municipality. the main objective of the proposed work is to create a flexible application that dynamically solve the issue of late bin clearance, poor management of bins etc. the path selection is made by using the Travelling Salesman Algorithm in the Dynamic programming approach. the sensor network is utilized to gather information regarding the garbage contents in the bins and remotely trigger the request for a cleaning process using the Internet of things. the internet is connected with microcontroller hardware using a Node-MCU device, or ESP8266, a small internet-supporting module that works as a plug-and-play module to any microcontroller. the primary objective of this system is to send information to the municipality and the mobile application regarding the status of the bin, the minimum cost path, the total travel distance, and the kind of vehicle required. this system aims to shorten travel time, save money on diesel and human resources for garbage collection, and improve waste collection and monitoring.

the Haskell String type is notoriously inefficient. We introduce a new data type, ByteString, based on lazy lists of byte arrays, combining the speed benefits of strict arrays with lazy evaluation. Equational transformations based on term rewriting are used to deforest intermediate ByteStrings automatically. We describe novel fusion combinators with improved expressiveness and performance over previous functional array fusion strategies. A library for ByteStrings is implemented, providing a purely functional interface, which approaches the speed of low-level mutable arrays in C.

this paper presents the solution for odd and even number of switching angles of harmonic elimination pulse width modulation (HEPWM). HEPWM capable to eliminate low order harmonics of inverter output voltage by solving the transcendental equation of the switching angles. the optimum switching angles are calculated using differential evolution (DE) algorithm. DE is simple and effective algorithm. the calculated switching angles applied to the three-phase voltage source inverter (VSI) and harmonic performance of output voltage are examined using MATLAB/Simulink software. the Total harmonic Distortion (thD) of line to neutral of inverter is analyzed for different number of switching angles. the simulation result showed that the low order harmonics, namely 5th, 7th, 11th, 13th, 17th, 19th, 23th was eliminated individually by N=3,4,5,6,7 and 8.

this paper presents a new programming method, called the data transform programming method. In particular, we present a specialization of data transform programming to deal with file processing applications. Direct comparison is made with Jackson's approach1 by the presentation of uniform solutions to problems that cannot be solved through his basic method. the new method consists of the application of data transformations to the abstract problem statement, following the formal notions of problem reduction and problem decomposition. Data transformations are expressed in programming terms through a basic set of data type constructors.

the attendance of employees was recently seen as one of the most important elements or issues in paying salaries. Various automatic identification technologies such as radio frequency identification have been more popular (RFID). A wide range of research and other applications have been produced to maximize this technology and express certain concerns. RFID is a wireless equipment that uses data move from an electronic tag, identify as RFID tag, or label for sending data to RFID reader, for the rationale of classify and pathway objects via radio waves. In addition to the programmable logic circuit, such as Arduino, the current study aims at recommending an RFID based Attendance Management System (AMS), as well as a system of information services on academic domains. the system proposed is aimed at managing the attendance system of employees with RFID tags/stickers to communicate with an Arduino UNO connecting RFID Reader/Writer module. the Arduino UNO receives authentication data, which is then sent through an Ethernet module, to Google Spreadsheets in order to store and access data in real time. the attendance system is therefore non-paper and organized because of the timestamp, the card key and the columns on the API table.
