Artificial Lift systems are routinely employed in the petroleum industry in order to provide the energy needed for the fluid to be transferred from the reservoir to the surface. The ESP system is a method of artificial lift widely used in recovery, often applied in mature fields or fields with heavy oil (low API gravity), as well as high flow rate wells. The energy for ESP systems is supplied by a...
Autism is a neurological developmental disorder that occurs in 1 out of every 88 births and affects males more often than females by a 4:1 ratio. This brain-based disorder affects a child's ability to communicate and interact socially and typically becomes evident within the first 3 years of life. Teaching Aid Software (TAS), with its integrated view into the requirements and interests of children,...
This study focuses for the first time on the water stress detection and discrimination among different stages of red palm weevil (RPW) stress-attacks using water stress indices (WSI) and linear and second order polynomial statistical analysis. Different WSI were assessed using new technology Worldview-3 (WV-3) simulated data. Based on field identification, five palm tree classes were considered: dead,...
The acquisition and collation of large numbers of spectral measurements of samples requires the strict adherence to set protocols to ensure the integrity of the data. Errors can occur in the measurement or processing that may not initially be detected and would require the time-consuming process of re-measuring of samples. This paper outlines the development of a national spectral library, and, the...
Reed-Solomon (RS) code is one of the most widely used error control codes. The decoding algorithms of RS code can be briefly divided into hard-decision decoding (HDD) and algebraic soft-decision decoding (ASD). However, traditional RS decoding algorithms perform unsatisfactorily over bursty channel. Therefore, many modified RS decoding algorithms utilised in bursty channel decoding were proposed....
Autism is a developmental disorder involving qualitative impairments in social interaction. One source of those impairments are difficulties with facial expressions of emotion. Autistic people often have difficulty to recognize or to understand other people's emotions and feelings, or expressing their own. This work proposes a method to automatically recognize seven basic emotions among autistic children...
Functional and structural connectivity convey different information about the brain. The integration of these different approaches is receiving growing attention from the research community, as it can shed new light on brain functions. This manuscript proposes a constrained autoregressive model with different lag-orders generating an “effective” connectivity matrix which models the structural connectivity...
There are different kinds of technologies being used to improve the communication opportunity of children with verbal challenges. Portable communication devices provide the facility to the users for customizing applications according their needs. Besides, the usability and costing range of these portable communication devices make them less condemning for the users. On the other hand, communication...
Using technology to improve the life-style of people with special needs has become a hot research topic in today's world. The making of a smart device that can solve the communication issues faced by people with autism spectrum disorder(ASD) and disability is presented in this paper. Fueled by the intent of bridging the communication gap between these people and the rest of the world, we have built...
In this work, we focused on classification of the participants with Attention Deficit Hyperactivity Disorder (ADHD), Autism Spectrum Disorder (ASD) and typically developing children, based on their performances during an emotion recognition experiment that we developed. We prepared an experiment environment where participants were shown images of faces of people exhibiting certain emotions up to a...
Determining the suitability of a medium-voltage motor which will be installed within a hazardous location as outlined in IEEE 1349, powered by a multi-level, voltage source, adjustable speed drive that is not isolated by a phase-shifting transformer requires two key items to be investigated — thermal heating due to the current harmonics, and the energy contained in uncontrolled sparking from the motor...
An Offshore Oil & Gas Service vessel equipped with DC Propulsion Drives retrofitted with revenue generating equipment such as Remote Operated Vehicles (ROVs) and cranes, could not pass Sea Trials due to multiple failures (including loss of navigation) caused by harmonic distortion. Marine propulsion systems represent a dominant load on most vessels and dynamically positioned (DP) offshore installations...
A pipe line pump station experienced failure of the dry-type, 2.5MVA, medium voltage, Adjustable Speed Drive (ASD) Input transformers called ASD-2 and ASD-5, on three different occasions. The authors conducted a failure investigation involving on-site measurements and transformer tests, as well as transient modeling of the system and recommended solution. The key to understanding the failures were...
Adjustable speed drive (ASD) and motors, if selected as a prime mover for compressors, pumps, extruders, etc. can provide various electro-mechanical benefits to its operators and stakeholders. Their benefits and application considerations have been well documented in past papers and tutorials. However, a successful installation of a multi-megawatt motor and ASD system requires detailed application,...
Autism is a lifelong, developmental disability that affects how a person communicates with and relates to other people. It is defined by a certain set of behaviours such as, Facial Expression of Emotion. Autistic people often have difficulty recognising or understanding other people's emotions and feelings, or expressing their own. Such difficulties can make it very hard for autistic people to navigate...
Problems with joint attention (JA) are core features of Autism Spectrum Disorders (ASD). Here, we investigate how typically developing (TD) children and children with ASD respond to joint attention (RJA) and initiate joint attention (IJA) with a gaze contingent avatar. Thirty-one participants with ASD and 33 TD matched controls followed and directed the avatar's gaze to a series of referent images...
Autism Spectrum Disorder (ASD) has been suggested to associate with alterations in brain connectivity. In this study, we focus on a fiber clustering tractography segmentation strategy to observe white matter connectivity alterations in ASD. Compared to another popular parcellation-based approach for tractography segmentation based on cortical regions, we hypothesized that the clustering-based method...
Sizing prime and backup generator packages for non-linear loads, (such as adjustable speed drives, solid state UPS systems, DC Drives and other SCR loads and even single phase loads such as computer systems, ballasted lighting and other power electronic loads), is not a simple process. Including the effects of the non-linear load harmonics is essential to properly sizing generator capacity. Incorrectly...
Large high speed induction motors are being utilized more and more in the Oil & Gas industry to drive compressors. These machines are of particular interest for offshore installations as they significantly reduce the installed foot print. Due to the specific needs of offshore construction and commissioning programs, it is very important for the end users to validate as much as possible the drive...
Robots are often employed to proactively engage children with Autism Spectrum Disorder (ASD) in well-defined physical or social activities to promote specific educational or therapeutic outcomes. However, much can also be learned by leveraging a robot's unique ability to objectively deliver stimuli in a consistent, repeatable way and record child-robot interactions that may be indicative of developmental...
