Quantifying the effects of airflow distortion on anemometer wind speed measurements from merchant ships

Anemometers on Voluntary Observing Ships (VOS) are usually located above the bridge in a region where the effects of air flow distortion, created by the presence of the ship, may be large. Until now it was not known whether measurements from such anemometers would be biased high or low, and the possible magnitude of any such bias was not known. Investigations into the airflow above merchant ships have been carried out experimentally using a low-speed wind tunnel and numerically using a commercial Computational Fluid Dynamics (CFD) code VECTIS. The investigations examined the airflow over simple block models of VOS shapes. The results of the investigations were compared to wind speed measurements made from the RRS Charles Darwin. Experimental and CFD techniques have been used to devise scaling rules that predict the effects of the flow distortion. Both techniques have shown that the pattern of the flow distortion above the bridge scales with the ‘step height’, H, of the model. In the case of a tanker, H is the ‘bridge to deck’ height, i.e. the height of the accommodation block above the deck, for bow-on flows. Close to the top of the bridge the flow is severely decelerated and may even reverse in direction. Using the upwind edge of the bridge as the origin of the scaled co-ordinate system, there is a definite line above the decelerated region along which the speed of the flow is equal to the undistorted wind speed. Above this ‘line of equality’ the wind speed increases to a maximum and then decreases with increased height to a free stream wind speed. Simple equations have been devised to predict the positions of the ‘line of equality’, the maximum wind speed and the minimum wind speed within the decelerated region. Comparisons of the results with wind speed data obtained from field measurements made using a number of anemometers located on the RRS Charles Darwin agreed well and have predicted a maximum wind speed increase of approximately 15 ±5 %. Comparisons with the field data have confirmed that CFD models can be used to predict the effects of airflow distortion above merchant ships. The investigation has demonstrated the ability of the wind tunnel and CFD approaches employed to provide a better understanding of the airflow over merchant ships. Both methods have contributed to improve the understanding of how the wind speed at anemometer sites on merchant ships is affected by the ships hull and superstructure.

Low temperature power generation using HFE-7000 in a Rankine cycle

This thesis presents the modeling, construction, and testing of a cost-effective Rankine cycle that utilizes a low-grade heat source (100? C); a non-toxic, environmentally benign working fluid (heptafluoropropyl methyl ether, or HFE-7000); and a scroll-type expander to generate electric power. A thermal efficiency of 3.1% was achieved, and a clear path forward has been presented to achieve 9.7% efficiency. This experiment validates the use of HFE-7000 as a working fluid in a Rankine cycle – both in a custom application or as a drop-in replacement for less-desirable fluids. Such a system has potential uses that include bottoming cycles for industrial processes and inexpensive non-concentrating solar-thermal power plants.
NGL Recovery Enhancement for GUPCO Trans Gulf Gas Plant by using New Applicable Technique

It is known that the price of natural gas liquids (NGL) is higher than that of natural gas from which it is derived, so more modifications needed for existing plants to derive more NGL is economically accepted point of view. The main objective of the present work is to present the method applied on Trans gulf (T/G) gas plant to overcome its performance decrease happened after the plant feed gases becoming leaner than its design margin and hence it led to a great decrease in the plant NGL recovery. This achieved by introducing a new simple modification to the existing process scheme obtained by using a condensate stream to enrich the reflux of the de-ethanizer tower so more recovery is obtained. In order to accomplish that goal, some changes in the existing process operating conditions were needed. A simulation is used in this study to examine the existing and the introduced modification utilizing ASPEN-HYSYS software version 8.4 using Peng-Robinson equation of state (EOS). The simulation of the existing plant results in a better understanding of the plant behavior in the different iterations to reach the maximum benefits. The plant after suffering from low butane recovery from its feed gas and which considered as a figure to the plant efficiency, it increased by this method from 38 % to reach 86-90 % butane recovery and its LPG production increased by 170% to be ≈ 122 tonne/day instead of ≈ 44 tonne/day while only losing ≈ 16 tonne/day of condensate production. An optimization to the new method is done in this paper so that it doesn't intercept with the existing plant equipment performance for the process safety triggers. Also, the last section of the study describes the economic point of view and the return on investment (ROI) how it was paid back only in 7 days. This modification can be taken as a guideline for both new and existing LPG plants which use only propane refrigeration systems for LPG recovery to increase their profits with the lowest cost possible.
“Take over!” How long does it take to get the driver back into the loop?

Raising the automation level in cars is an imaginable scenario for the future in order to improve traffic safety. However, as long as there are situations that cannot be handled by the automation, the driver has to be enabled to take over the driving task in a safe manner. The focus of the current study is to understand at which point in time a driver’s attention must be directed back to the driving task. To investigate this issue, an experiment was conducted in a dynamic driving simulator and two take-over times were examined and compared to manual driving. The conditions of the experiment were designed to examine the take-over process of inattentive drivers engaged in an interaction with a tablet computer. The results show distinct automation effects in both take-over conditions. With shorter take-over time, decision making and reactions are faster but generally worse in quality.
Prolonged Exposure Therapy for PTSD

This therapist guide of prolonged exposure (PE) treatment is accompanied by the patient workbook, Reclaiming Your Life from a Traumatic Experience. The treatment and manuals are designed for use by a therapist who is familiar with cognitive behavioral therapy (CBT) and who has undergone an intensive training workshop for prolonged exposure by experts in this therapy. The therapist guide instructs therapists to implement this brief CBT program that targets individuals who are diagnosed with posttraumatic stress disorder (PTSD) or who manifest PTSD symptoms that cause distress and/or dysfunction following various types of trauma. The overall aim of the treatment is to help trauma survivors emotionally process their traumatic experiences to diminish or eliminate PTSD and other trauma-related symptoms. The term prolonged exposure (PE) reflects the fact that the treatment program emerged from the long tradition of exposure therapy for anxiety disorders in which patients are helped to confront safe but anxiety-evoking situations to overcome their unrealistic, excessive fear and anxiety. At the same time, PE has emerged from the adaption and extension of Emotional Processing Theory (EPT) to PTSD, which emphasizes the central role of successfully processing the traumatic memory in the amelioration of PTSD symptoms. Throughout this guide, the authors highlight that emotional processing is the mechanism underlying successful reduction of PTSD symptoms.
Messy Ecosystems, Orderly Frames

Novel landscape designs that improve ecological quality may not be appreciated or maintained if recognizable landscape language that communicates human intention is not part of the landscape. Similarly, ecologically valuable remnant landscapes may not be protected or maintained if the human intention to care for the landscape is not apparent. Landscape language that communicates human intention, particularly intention to care for the landscape, offers a powerful vocabulary for design to improve ecological quality. Ecological function is not readily recognizable to those who are not educated to look for it. Furthermore, the appearance of many indigenous ecosystems and wildlife habitats violates cultural norms for the neat appearance of landscapes. Even to an educated eye, ecological function is sometimes invisible. Design can use cultural values and traditions for the appearance of landscape to place ecological function in a recognizable context. I describe several examples of cultural language “cues to care” that provide a cultural context for ecological function, and I demonstrate how these cues can be used in design.
EVALUATING TESTER EXPERIENCE IN AN INDUSTRIAL ENVIRONMENT: AN EXPERIENCE REPORT

Software testing is essential to guarantee product quality. As such, while technologies, automation, and systematic methodologies are important, the human aspects of testing, that is, the individual performing the activity, certainly does matter in software testing. As a result, Tester Experience (TX) has been defined to bridge the gap between technical and human aspects of software testing. TX can identify influence factors that can affect test effectiveness from testers' perspective. In this paper, we present our experience, through previous results, where we evaluate TX in the Google Approval (GA) homologation team, with 27 subjects of SIDIA Institute of Science and Technology. The results show that TX successfully captured participants’ experience with respect to their daily activities and artifacts. In addition to this, TX was also able to point out points for improvement within the GA team.

Penggunaan Kembali Air Limbah – Pengolahan Air Limbah Domestik untuk Suplai Kebutuhan Air Pertanian

Wastewater reuse arises in line with the increasing demand for water amidst the water scarcity crisis. An alternative solution of water sources for water supply that is possible in this case is the wastewater reuse. The agricultural sector is the focus of water supply because the water quality required does not require the best water quality, but still before wastewater reuse must be treated first. The complexity of wastewater characteristics is another absolute consideration in determining the source of wastewater for water supply, domestic wastewater has characteristics that are not too complex and relatively safer than industrial wastewater. The choice of domestic wastewater also has an impact on water treatment, which in principle can be done simply, but the main problem in wastewater is related to its pollutants content. The concept of wastewater treatment with Constructed Wetland (CW) is fairly easy to implement and the results of reducing physical and chemical pollutants are up to 40-70%, reduction of biological pollutants is estimated to be insignificant so it needs to be combined with disinfection to reduce the content of microorganisms in the effluent which is expected to meet quality standards. The main priority is to provide water supply to agricultural land on a small scale or to be used for supporting water supply on large agricultural lands with agricultural activities that do not really need water in a continuous time.
Stabilization of inverted pendulum using hybrid adaptive neuro fuzzy (ANFIS) controller

The basic aim of our research was to design an appropriate fuzzy logic controller using ANFIS for controlling the cart and pendulum assembly of an Inverted Pendulum. A Neuro-fuzzy hybrid approach was used to train the ANFIS based controller. The training data sets were taken from previously occurred simulations. The ANFIS controller learns the training data quickly with a very low amount of error tolerance. The controller was designed in the Matlab-Simulink environment and the results are shown in the end. The results proved that ANFIS controller has good stabilization capability as compared to the fuzzy logic controller. Also a comparison is given which shows the effect of changing the shape of certain linguistic variables on the control of Pendulum.
Virtual co-creation - A mixture between control and freedom

The purpose with this study is to enhance our knowledge about virtual co-creation by investigating in the underlying role of the co-creating consumer and how companies manage co-creation as well as studying how power is distributed within this consumer- company relationship. The research undertakes a qualitative research strategy with an abductive methodological approach. Netnography is the chosen research method for collecting primary data and a literature study for collecting secondary data. The theoretical dimension is built on theories regarding virtual co- creation, the roles of production and consumption, space and place and post-modernistic views of co-production and the management of free labour. Empirics are collected through online observations taking the part as complete observes of the chosen empirical site, LEGO “DESIGNbyME”. Empirical results are analyzed with a base in the theoretical dimension by applying theories regarding the role of the consumer and the management of free labour on the “DESIGNbyME” site. Co-creation is a mixture of control and freedom, where companies can by strategies control the place but only to some extent in order to not limit the space of the consumer to enfold their creativity.
Attachment Security

This chapter provides an overview of the construct of attachment security and describes the threat to this security that may arise in response to the diagnosis or progression of advanced disease. The heightened mortality salience that occurs in this context activates the attachment system, and increased dependency and caregiving needs frequently require an adjustment or renegotiation of attachment security. Attachment security protects from death anxiety and other forms of distress, and so the renegotiation of attachment relationships is often an urgent task that is needed to maintain or restore emotional equilibrium. This chapter explains the central role of attachment security in the Managing Cancer and Living Meaningfully (CALM) intervention, in which the therapeutic relationship can provide a secure base to process distressing thoughts and feelings and to face the challenges that inevitably occur.

In a study with a leading company, systematic use was made of qualitative data collection methods to elucidate existing practice. Analysis of the data led to suggestions for improvement in procedures and the development of a computer based aid for estimation.
Novel methods and circuits for field shaping in deep brainstimulation

Deep Brain Stimulation (DBS) is a clinical tool used to treat various neurological disorders, including tremor, Parkinson’s disease (PD) and dystonia. Today’s routine use of this therapy is a result of the pioneering work of Benabid and colleagues, who assessed the benefits of applying high-frequency stimulation to the ventral intermediate nucleus and reported substantial long-term improvements in PD patients. Clinical applications of DBS, however, have preceded research and left a number of challenges to optimise this therapeutic technique in terms of quality, therapy costs and understanding of its underlying mechanisms. DBS is based on monopolar or bipolar stimulation techniques, which are characterised by a limited control over the effects of stimulation and, in particular, over the shape and direction of the electric field propagating around the electrode. This thesis proposes two approaches to achieve dynamic electric field control during deep brain stimulation. The first method is based on the use of current-steering multipolar electrode drive, adopted to split the stimulation current between 2 or more contacts, in order to shift the stimulation field to a desired location. The work included the design, development and testing of an integrated circuit current-steering tripolar current source, developed in AMS 0. 35μm technology. The second method is based on the use of phased arrays (PAs) in order to create an electromagnetic beam, which can be steered to a desired location. Computational models have shown the ability to steer and focus the electromagnetic fields in brain tissue by varying the phase and frequency of stimulation. Modelling simulations have shown that the use of multipolar electrode configurations is essential to achieve dynamic control over the shape and area of tissue stimulated. Configurations with larger number of cathodes allow for several stimulation patterns, making this stimulation approach beneficial in a clinical environment. Tests on the performance of the integrated tripolar current source have shown its capability to generate stimulation currents up to 1.86mA, to linearly steer the stimulation current to one of the anodes and to generate biphasic square and exponential current pulses, with time constant up to 28ms. In vitro experiments, carried out to map the electric potential generated by a dynamic tripolar current source, validated the model results, by showing the ability to shape the potential distribution around the electrode during stimulation. Finally, models of the behaviour of PA fields in brain tissue have shown that PAs could be introduced to DBS to allow for more accurate field steering and shaping in DBS. This thesis presents methods and implementations to achieve dynamic field shaping in DBS, which can greatly ameliorate the efficacy of clinical DBS.
Understanding and monitoring cloud services

Cloud services have changed the way computing power is delivered to customers. The advantages of the cloud model have fast resulted in powerful providers. However, this success has not come without problems. Cloud providers have been related to major failures, including outages and performance degradation. Similarly, privacy of cloud services is of huge concern for exposing users to providers and foreign governments. We argue that dependability concerns will impel enterprises to require assurances and independent monitoring of their services in the cloud. Privacy issues will prompt new players to offer services that combine the strengths of cloud computing with stronger privacy. Initial signs of both trends can already be mentioned, such as companies offering independent tools to monitor cloud performance and regional players entering the cloud market while worldwide firms hesitate to trust international providers. This thesis has two objectives. Firstly, we investigate simple and scalable methods for monitoring the performance of cloud services, aiming to provide means for customers to monitor their services easily and independently. Secondly, we study how cloud services are implemented and the implications of their design and usage for the Internet, aiming to foster the development of new services. We focus on cloud storage, because it is a popular application accounting for a significant share of Internet traffic. Our main contributions are the following: (i) we introduce a novel method to monitor the performance of cloud services, relying on flow measurements collected from customers' networks; (ii) we present the first characterization of cloud storage, revealing its typical usage and possible performance bottlenecks; and (iii) we evaluate the implications of design choices for both users and the Internet, by comparing different providers in a series of benchmarks. Our analyses show that cloud services can be monitored using information available at customers' networks. Our results make clear that cloud storage is data-intensive and understanding its usage is essential for building well-performing services. Our comparisons of providers demonstrate that design differences that seem minor can result in surprisingly costs and performance bottlenecks. Our contributions are valuable for companies outsourcing to the cloud and for engineers developing cloud storage, and can assist new players to build the next generation of cloud storage services.
