Since antiquity, architects have been using simple guides or easy to use calculation methods called rules of thumb for predicting daylighting performance inside buildings. These rules of thumb in daylighting continue to develop as new knowledge in science and technology evolves. In architectural practice, daylighting rules of thumb have often been expressed in terms of the percentages of window area to floor area. Such rules can be found in architectural literatures as well as in building regulations in various countries. The percentages of window glazing area to floor area suggested in the literatures and building codes often range from 10% to 35% depending on the specified visual tasks and the illumination characteristics desired. One of the most frequently cited daylighting rules of thumb is for 20% glazing to floor area allocated for habitable room or space. These rules of thumb are usually based on the standard clear glass with transmittance value of approximately 0.8 to 0.9. However, many recent buildings in tropical countries have glazing transmittance lower than this value for glare control and privacy purpose. In order to address this issue, daylighting simulations were conducted using AGi-32 to determine the effects of different glazing transmittances on indoor daylight performances and to modify existing rule of thumb. Based on the simulation data and analysis, a well-known daylighting rule of thumb by Littlefair is modified to cater for multiple glazing transmittances. This new rule of thumb presents an easy to use calculation to estimate daylight factor for interior based on glazing transmittance value.

This article discusses the problems of the acoustic emission method of non-destructive testing. An approach to filtering noise arising from monitoring of acoustic emission is considered. The filtering of acoustic noise is one of the key problems of the acoustic emission method, since the low noise immunity of the acoustic emission method prevents the expansion of its industrial application. The complexity of the filtering is explained by the fact that the waveform and spectrum of acoustic emission pulses change depending on the distance between the defect, which is the source of acoustic emission waves, and the sensor. In turn, the interference, as a rule, is non-stationary in nature and is determined by the type of technological process of the tested composition. This article discusses various types of noise processes, both stationary and non-stationary. The signal and noise parameters are compared, based on which recommendations are given for constructing algorithms for detecting acoustic emission pulses against a background of noise.

Utilization of renewable energy for the reduction of fuel consumption and green house gas (GHG) emissions in the shipping industry has been increased rapidly in the recent years. Wind energy is a clean renewable energy with no pollution which is abundantly available at sea. This paper proposes two different possible configurations of connecting wind power energy into the ship’s main grid bus system . Wind electrical energy output has been connected to ship’s main ac bus system in one configuration and it is connected to ship’s main dc bus system. Even though Wind assisted ship propulsion (WASP) had been started already in the last decades in the form of wing sails, kites, Flettener rotor etc which could assist auxiliary propulsion of the ships, the application of wind power generator on the ship is not often applied. Therefore this paper has a relevant significance in applying wind electrical energy for the marine electrical power system needs. This paper also reveals the benefits and challenges in the area of onboard wind generation and opens future research possibilities in integrating wind energy into marine industry.

Voltage to frequency converters are used in various types of analog to digital converters in suitable digital audio applications. One of the applications is the Audio Interface which has been considered. The Voltage to frequency converter (VFC) thus plays a major role in the analog to digital conversion. This paper proposes a low power VFC designed in 0.18 μm technology which in turn is used to design a low cost and a high-resolution analog to digital converter (ADC). The analog signal is given to the V-F converter and the VFC output is given to the frequency counter using a suitable link. This counter gives the digital output. The design is implemented in PSoC and the performance is analysed with the previous technologies. Parameters such as sensitivity, output frequency and power consumption are analysed. This V-F converter and ADC are used in the digital audio interface which is used for audio applications. With the proposed VFC and ADC, the interface produced a good SNR compared to the conventional audio interfaces.

Due to the development of road infrastructure and business trade, transportation of goods is increasing day-by-day. Each vehicle has its own configuration, size, power and capacity. However, heavy vehicles are often used to carry loads beyond their capacity. Therefore overloading is one of the major problems which affect truckers as well as other motorists and pedestrians going near-by. In order to provide a convenient solution to this problem, a web-based tracking system is proposed. A heavy duty vehicle which is overloaded and moving at high speed may cause the vehicle to loose balance while making turns along the roads. This problem may also cause the tire to burst, which in turn makes it difficult to control the vehicle. Communication module is interfaced with a microcontroller which takes data from global positioning system receiver to locate the current position of the overloaded vehicle. This unit is majorly controlled by an electronic control unit. A sensing element is placed at the axle point of the vehicle to concentrate on the total weight of the vehicle. A software study is done to extract the global positioning system data from GPRMC format. The proposed system is simulated and tested for semi-real data. The received data is transmitted to the control room user for further improvement in traffic regulation and road safety.

Financial Fraud, for example, tax evasion, is known to be a genuine procedure of wrongdoing that makes misguidedly got assets go to psychological warfare or other crime. This sort of criminal operations include complex systems of exchange and money related exchanges, which make it hard to recognize the extortion elements and find the highlights of fraud. Luckily, exchanging/exchange system and highlights of elements in the system can be developed from the mind boggling systems of exchange and money related exchanges. Exchanging/exchange system uncovers the association among substances and consequently irregularity discovery on exchanging systems can uncover the elements engaged with the misrepresentation movement; while highlights of elements are the depiction of elements and abnormality identification on highlights can reflect subtleties of the extortion exercises. In this manner, system and highlights give integral data to extortion discovery, which can possibly improve fraud recognition execution. Nonetheless, most of existing strategies center on systems or highlights data independently, which doesn't use both data. In this paper, we propose a novel fraud identification framework, CoDetect, which can use both system data and highlight data for money related extortion discovery. What's more, CoDetect can all the while identifying money related fraud exercises and the component examples related with the extortion exercises. General examinations on both real world information and certifiable information exhibit the productivity and the adequacy of the proposed structure in battling monetary extortion, particularly for tax evasion.

Nowadays, users of the internet are becoming increasingly popular, because of this rising load packets of network and delay requests. In this paper, we offer a method to improve allocation resource in the IMS servers. Implementation of technology for balancing of loading in practice allows to optimize the decision of distribution tasks of signal and information flows on telecommunication networks. In case of uniform loading of the IMS servers and routers of a backbone network (devices of the network), the average time of a time delay of signal and information packets is minimum. Uniformity of loading of network devices is reached due to the uniform distribution of a flow of packets. The criterion of efficiency of methods of distribution of flows is the average square deviation (a balanced index) of congestion of network devices. AnyLogic 7 agent system toolbox is used to simulate the proposed system.
