The Theological Origins Of Engineering, Brad Kallenberg

Brad J. Kallenberg

Knowledge of our roots can sometimes help us figure out how we ought to proceed. Many claim that engineering began in ancient antiquity with the Egyptian pyramids, Archimedes' inventions, or the Roman aqueducts. Others give contemporary engineering a more recent history, tracing its origins to the Industrial Revolution or the Enlightenment. Yet what is often overlooked is the fact that contemporary engineering owes part of its identity to medieval monasticism. The advantage of remembering this history is the bearing it has on the questions "What is engineering for?" and "How ought engineering be practiced?" Michael Davis makes the claim that, …

Investigation On The Soundscape Preference And Perception Of Highlands Environment: A Preliminary Study, Nazli Che Din, Engku Mastura Engku Ahmad, Hazreena Hussein

Hazreena Hussein

Highland environment is one of the popular tourist destinations because it holds a rich array of natural resources. However, the economic and development growth of highlands gave potential effect of biological wealth and environment surrounding. Noise pollution in developing highland area could intrude the ability to comprehend of natural and environmental sounds. As preliminary, the main objective of this research is to identify factors and elements that characterise the soundscape in three selected green areas on highland environment. The research was carried out through a series of field measurement and audio-visual experiment. At the first stage of the study, the …

Effect Of Fibre Blend Ratios On Yarn Properties, Innovative Research Publications Irp India, A. Ghosh, M. Raihan

Innovative Research Publications IRP India

Yarn properties can be altered through blending fibres. According to the requirement different properties can be achieved by different blending ratios. Among the different blends cotton and polyester, cotton and wool, wool and acrylic, cotton and nylon, jute and acrylic, cotton and rayon etc are common. Flax and polyester has been a popular blend now-adays and depicts excellent properties than their individual yarn properties. Different proportion of flax and polyester has been tested to observe the yarn properties and it is found that polyester was perfectly fits with low proportion of flax. Their blends with specific ratios exhibit excellent properties …

Aliasing Reduction In Staring Infrared Imagers Utilizing Subpixel Techniques, Joseph C. Gillette, Thomas M. Stadtmiller, Russell C. Hardie

Russell C. Hardie

We introduce and analyze techniques for the reduction of aliased signal energy in a staring infrared imaging system. A standard staring system uses a fixed two-dimensional detector array that corresponds to a fixed spatial sampling frequency determined by the detector pitch or spacing. Aliasing will occur when sampling a scene containing spatial frequencies exceeding half the sampling frequency. This aliasing can significantly degrade the image quality. The aliasing reduction schemes presented here, referred to as microscanning, exploit subpixel shifts between time frames of an image sequence. These multiple images are used to reconstruct a single frame with reduced aliasing. If …

Anomaly Detection In Hyperspectral Imagery: Comparison Of Methods Using Diurnal And Seasonal Data, Patrick C. Hytla, Russell C. Hardie, Michael T. Eismann, Joseph Meola

Russell C. Hardie

The use of hyperspectral imaging is a fast growing field with many applications in the civilian, commercial and military sectors. Hyperspectral images are typically composed of many spectral bands in the visible and infrared regions of the electromagnetic spectrum and have the potential to deliver a great deal of information about a remotely sensed scene. One area of interest regarding hyperspectral images is anomaly detection, or the ability to find spectral outliers within a complex background in a scene with no a priori information about the scene or its specific contents. Anomaly detectors typically operate by creating a statistical background …

Optimization Of A Photovoltaic Pumping System In Bejaia (Algeria) Climate, Rahrah Karima Jr, Djamila Rekioua Pr

REKIOUA Djamila Dr

Photovoltaic energy is used in different applications and especially in water pumping and irrigation in remote areas. However, the performances of a photovoltaic pumping system can be degraded with variations of insolation and in order to maximize the efficiency of the photovoltaic energy system, it is necessary to track the maximum power point of the PV array. Many methods have been developed to determine the maximum power point (MPP). In this paper we present the results of performance optimization of a PV pumping system in Bejaia (Algeria) climate. The pumped water is desired to satisfy the domestic needs of three …

Control Of Photovoltaic Water Pumping System, Chafia Serir Jr, Djamila Rekioua Pr

REKIOUA Djamila Dr

Due to the continuous decrease of the solar cells cost, photovoltaic energy is used in different applications. The most important one is the water pumping system powered by photovoltaic generators. These systems can work with or without storage battery. With the increased use of this application, more attention has been paid to their optimum utilization. Many methods have been developed to determine the maximum power point (MPP). In this paper, to control the DC bus voltage, we apply field oriented control (FOC) strategy to induction motor (IM) supply by a photovoltaic (PV) system. And to maximize the efficiency of the …
