The Roles of Switching Barriers and Corporate Image between user Experience and Loyalty in Indonesia Mobile Network Operators

Recently, the competition among mobile network operators in Indonesia is getting tight that was shown by the price war and the saturated condition. Mobile network operator is the fastest growing companies in telecommunication sector that causes user has a wide range of selection. Previous authors believed that users will tend to be loyalty when they faced too many barriers to switch to other operator. Besides that, users also make a consideration regarding to the corporate image of their operator. This study has an intention to examine the effect of switching barriers and corporate image on the relationship between user experience and loyalty. Out of 400 respondents were obtained by quota sampling technique with 66 questionnaire items in Indonesia showed that switching barriers mediate the relationship between user experience and loyalty with the greatest value came from the relationship among perceived service quality, switching barriers, and loyalty. It implies that users will be loyal when they met too many barriers to become a switcher, at the time they perceived service quality in excellent condition. At the same time, corporate image strengthen the relationship between monetary and switching barriers, meaning that the relationship between monetary and switching barrier became stronger when users’ perceived corporate image was high.
An Investigation on Optimal Designing of Dynamic Vibration Absorbers Using Genetic Algorithm

Abstract. In this study reducing of the unwanted phenomenon in machine tools, Vibration, has been investigated. The machine tools has been simulated as a five-degree-of-freedom discrete system consisting of cutting tool, work piece, body, head and cantilever of the machine. In order to reduce the undesired vibrations, a dynamic vibration absorber (DVA) with three unknown parameters (mass absorber, damping coefficient , stiffness absorber has been added to the system in different positions. Utilizing Newton’s second law, the governing equations have been obtained and solved. A genetic algorithm is proposed to efficiently achieve the optimum value for each 3-fold parameters in each positions of the system. The effectiveness of the proposed algorithm and the designed DVA is evaluated through comparing the vibration amplitude of the machine tool in the presence and absence of the DVA, and the paper concludes the best place to situate the vibration absorber and its specifications.
Advanced In0.8Ga0.2As/AlAs resonant tunneling diodes for applications in integrated mm-waves MMIC oscillators

The resonant tunneling diode (RTD) is the fastest electron device to-date in terms of its ability to generate continuous-wave terahertz frequency at room temperature, owing to its unique characteristic of negative differential resistance (NDR). In this work, a lattice-matched In0.53Ga0. 47As (on InP) is used as the cladding layer, while a highly-compressive strained In0.8Ga0. 2As is sandwiched between two tensile-strained pseudomorphic AlAs barriers to form the active double barrier quantum well RTD structure grown by Molecular Beam Epitaxy. The ultimate aim of this work was to integrate an optimised RTD into an oscillator circuit to enable a 100 GHz (W-band) MMIC RTD oscillator.One of the key challenges in this work was to improve the DC performance of the RTD, through extensive material and structural characterisations. Growing nano-scale epitaxial layers require a high degree of controllability with mono-layer precision. The dependencies of the NDR components, such as the peak current density, peak voltage and peak-to-valley current ratio (PVCR) towards variations in structural thickness were studied systematically. Through this work, it is found that the peak current density is strongly affected by monolayer variation in barrier thickness. The effect of quantum well thickness variation towards peak current density is relatively weaker. Interestingly, variation in spacer layer thickness has very little influence towards the magnitude of the peak current density.The fabrication of the RTD using a conventional i-line optical lithography created its own challenge. The process capability to reduce mesa active area down to sub-micrometer level to reduce device? s geometrical capacitance for high frequency, THz applications has been made feasible in this work. The conventional i-line optical lithography was combined with a newly developed tri-layer soft reflow technique using solvent vapour resulted in sub-micrometer RTDs. The DC characterisation of the fabricated RTDs showed excellent device scalability, indicating a robust processing. This novel sub-micron processing technique with high throughput and repeatability is a very promising low cost technique.A collaborative effort between the University of Manchester and Glasgow paved the way towards the realisation of an integrated W-band RTD MMIC oscillator. The circuit-combining topology was designed by the High Frequency Electronics Group in Glasgow while the mask-layout and oscillator fabrication took place in Manchester. An active RTD from sample XMBE#301 with peak current density of 1.4 x 105 A/cm2 and PVCR of 4.5 was integrated into a 100 GHz MMIC oscillator to successfully produce a measured frequency of 109 GHz with an un-optimised 5.5 ? W output power at room temperature (mesa area = 4x4 ? m2).
Dynamics and Stability of Rolling Viscoelastic Tires

Current steady state rolling tire calculations often do not includetreads because treads destroy the rotational symmetry of the tire.We describe two methodologies to compute time periodic solutions of a two-dimensional viscoelastic tire with treads:solving a minimization problem and solving a system of equations.We also expand on work by Oden and Lin on free spinning rolling elastic tires in which they disovered a hierachy of $N$-peak steady state standing wave solutions.In addition to discovering a two-dimensional hierarchy of standing wave solutions thatincludes their $N$-peak hiearchy,we consider the effects of viscoelasticity on the standing wave solutions.Finally, a commonplace model of viscoelasticity used in our numerical experimentsled to non-physical elastic energy growth for large tire speeds. We show that a viscoelastic model of Govindjee and Reese remedies the problem.
Analisa Kinerja Implementasi Wireless Distribution System Pada Perangkat Access Point 802.11 G Menggunakan OpenWRT

Wireless network is one of the best alternative for building a practical computer network. In some public area such as parks and cafes also office buildings have now largely been equipped with hot spot facility so that the visitors can enjoy a wireless Internet service. In addition, several agencies and offices have been using wireless network to support the existing cable network. However, the implementation of wireless nework still rely on a cable network that became the backbone of the access points so that connected clients (laptops, PCs, etc.) can access the Internet. This wiring problem would be a significant constraint on the places that are difficult to reach. The Solution of this problem is to implement the Wireless Distribution System (WDS) on access point device. WDS is a system that develop a wireless Internet network without using of network cable as a backbone for the access point, but taking the advantage of the wireless line from the access point. In this final project, the implementation of WDS methods are analyzed to determine the impact of its application to the quality and channel capacity of wireless networks. From the analysis and observations it is known that the implementation of the WDS can reduce channel capacity up to 33% of capacity without the application of WDS Keyword : Wireless Network, Wireless Distribution System (WDS), Access Point, openWRT.
Land Use and Land Cover Mapping of Davangere using Google Earth Engine

Ever since the advent of modern geo information systems, tracking environmental changes due to natural and/or manmade causes with the aid of remote sensing applications has been an indispensable tool in numerous fields of geography, most of the earth science disciplines, defence, intelligence, commerce, economics and administrative planning. One among these applications is the construction of land use and land cover maps through image classification process. Land Use / Land Cover (LULC) information is a crucial input in designing efficient strategies for managing natural resources and monitoring environmental changes from time to time. The present study aims to know the extent of land cover and its usage in Davangere region of Karnataka, India. In this study, satellite image of Davangere during October-November 2018 was used for LULC supervised classification with the help of remote sensing tools like QGIS and Google Earth Engine. Six LULC classes were decided to locate on the map and the accuracy assessment was done using theoretical error matrix and Kappa coefficient. The key findings include LULC under Water bodies (8%), Built up Area (15.1%), Vegetation (9%), Horticulture (20.8%), Agriculture (39.3%) and Others (7%) with overall accuracy of 94.8% and Kappa coefficient of 0.866 indicating almost accurate goodness of classification
Elastic Comparison of Four Thread Forms.

Abstract : Previously, this author introduced the concept that all screw thread forms have a structural Characteristic Curve, which defines the basic stress concentration as a function of a radial stress in the joint. An additional set of characteristic curves is produced when the general stress field is considered. The standard analysis is for a single thread tooth, isolated from a long chain of identical teeth, that is computationally efficient and facilitates the calculation of a family of characteristic curves. This work presents the characteristic plots for four different threads, the 7 degree British buttress, a 15 degree asymmetric V, the 20 degree Benet buttress, and a special 30 degree V. These four threads were selected because they are or may be useful in high pressure systems. Together they suggest the possibility of a standard thread family for high pressure applications.
Following distances, braking capacity, and the probability of danger of collision between vehicles

Accidents sometimes occur, particularly on high speed roads, because the driver of a following vehicle cannot stop in an emergency without overtaking the rear of the vehicle ahead. Accidents of this kind are called close following accidents. Accident data are examined to try to form an estimate of the frequency of such accidents on motorways. The vehicle ahead may stop very suddenly if involved in a collision, but such extremely sudden stops are not the only danger. Because braking capacity varies from vehicle to vehicle there may be danger even if the vehicle ahead is braked hard. The chance that the following vehicle cannot stop in time if the vehicle ahead is braked as hard as possible may be estimated from the distribution of braking capacities among vehicles. The variation of this probability with following distance, speed, and reaction time is evaluated and the effect which larger following distances would have on capacity is considered (A).
Single-Pilot Workload Management

Integrated glass cockpit systems place a heavy cognitive load on pilots (Burian Dismukes, 2007). Researchers from the NASA Ames Flight Cognition Lab and the FAA Flight Deck Human Factors Lab examined task and workload management by single pilots. This poster describes pilot performance regarding programming a reroute while at cruise and meeting a waypoint crossing restriction on the initial descent.
A new IAEA Technical Report Series Handbook on Radionuclide Transfer to Wildlife

The IAEA Technical Report Series (TRS) handbook on transfer of radionuclides to human foodstuffs from terrestrial and freshwater systems has recently been revised during the EMRAS I programme [1]. The document updates the previous handbook (TRS 364) and constitutes an important source of information for transfer parameters for the human foodchain. Quantification of the rates of transfer of radionuclides through foodchains to humans has long been a key focus of radiation protection. More recently, there has been a move away from radiation protection being solely anthropogenic to one which also considers protection of the environment as recognised by both the IAEA [2] and the ICRP [3] in their Fundamental Safety Principles and revised Recommendations, respectively, both of which now include the need to protect the environment. To address these recommendations and safety principles, the consequences of radiological releases need to be considered in part by estimating an internal dose. To do this, the transfer of radionuclides to wildlife of interest needs to be quantified. In response to the need for a reference source of information on radionuclide transfer to wildlife, the IAEA initiated the development of a TRS handbook, which has been supported by interaction with the EMRAS II Working Group 5, (http://www-ns.iaea.org/projects/emras/emras2/working-groups/working-group-five.asp). The TRS handbook has been finalised and is currently going through the IAEA approval process. The TRS handbook provides equilibrium concentration ratio values for wildlife groups in terrestrial, freshwater, marine and estuarine environments. Wildlife is considered to include all non-domesticated plants, animals and other organisms including feral species (i.e. non-native self-sustaining populations). The TRS handbook provides IAEA Member States with transfer data for use in the radiological assessment of wildlife as a consequence of planned and existing exposure situations [3]. As an equilibrium approach is presented, these data are not directly applicable to emergency situations.
Human Activity Recognition Using Smart
phones

Human-centered computing is an emerging research field that aims to understand human behavior and integrate users and their social context with computer systems. One of the most recent, challenging and appealing applications in this framework consists in sensing human body motion using smartphones to gather context infor-mation about people actions. In this context, we describe in this work an Activity Recognition database, built from the recordings of 30 subjects doing Activities of Daily Living (ADL) while carrying a waist-mounted smartphone with embedded inertial sensors, which is released to public domain on a well-known on-line repos-itory. Results, obtained on the dataset by exploiting a multiclass Support Vector Machine (SVM), are also acknowledged.
Evaluation of AURORA as a tactical source region simulation. Contractor report

This memo compares the AURORA environment with that expected in an actual tactical source region environment. The primary interest in making the comparison is to evaluate the role that AURORA can play as a source region simulator for tactical systems of interest to the U.S. Army Comparisons are made between the electric and magnetic fields measured in AURORA and those computed using a four source model of AUR3D. Excellent agreement is found in the comparison between the magnetic fields. The computed electric fields show a fundamentally different behavior from those measured in AURORA.
Determination of Terrain Serviceability of Military Vehicles by GIS Relief Analysis

This paper analyses capabilities of terrain serviceability ofvehicles in regards to the ground features. Two key relief attributesrelated to the slope inclination are defined, as well as reliefforms quantitatively defined as deviations of height above sea-level. As the secondary attribute, the topographic wetness indexis estimated, which, in correlation with the drainage coefficientyields the wetness value index as an essential factor of passablenessin the conditions of harder and more intensive precipitations,that is to say, sudden snow melting. By application ofGIS analysis, based on the digital model of space heights alongthe Kupa River from Pisarovina to SiSinec, the values of primaryand secondary relief attributes have been calculated, andthe analysis of Landsat satellite images has been used to definethe values of vegetation cover. Based on these values and dataon the soil type, the layer of ground wetness has been estimated.Cross Country Mobility Program of ESRI company, withinGIS program package Arc View 3.3. has been used to set themarginal values of the defined relief parameters and to estimatethe levels of mobility for single vehicles in different terrain conditions.The comparison of the obtained results clearly indicatesa possible application of the defined data in the analysisof terrain serviceability of military vehicles, with regard to therelief features of the terrain. For full applicability of the model itis also necessary to define other attributes of mobility related tohydrographical, vegetation, pedological, anthropogenic andother ground features.
Description of a micro-mechanical testing system

In recent years, technological advances have significantly enhanced the capability to produce milli- and micro-sized components which may be incorporated into the design of small, less costly, reproducible and more reliable nuclear weapons components. Two promising micro-scale processing technologies are Silicon surface micromachining (SMM), a process derived from microelectronics fabrication, and LIGA, a process involving electrodeposition of metals into a polymeric mask containing very fine, sharp features. Complicated SMM structures with micron sized features such as microengines, gears and pop-up mirrors have already been successfully developed. As part of an overall broad effort to develop mechanical test capability of millisized and microsized structures, a mechanical test system has been designed and assembled with the primary goal of characterizing the mechanical properties of LIGA synthesized structures and materials. The current system utilizes many off-the-shelf items including an MTS 3,000 pound 1.0 inch travel hydraulic actuator and an Interface 100 pound load cell. Load, stroke and displacement control is provided by an MTS TestStar system and two 0.100 inch LVDT displacement gages situated in a parallel arrangement at the specimen. Load resolution is on the order of 50 {micro} oz. and displacement resolution less than 45 {micro} inch. The system can test dynamically up to 100 hz at 0.005 inch actuator displacement and loads of 100 lb. , statically at up to 250 lb. (limited by the load cell). The scope and flexibility of the microscale test system extends far beyond simply testing LIGA synthesized parts. A detailed description of the machine and a diverse set of results are presented in this report.
Two-arm Manipulation: From Manipulators to Enhanced Human-Robot Collaboration

This thesis is devoted to the study of robotic two-arm coordination/manipulation from a unified per- spective, and conceptually different bimanual tasks are thus described within the same formalism. In order to provide a consistent and compact theory, the techniques presented herein use dual quaternions to rep- resent every single aspect of robot kinematic modeling and control. A novel representation for two-arm manipulation is proposed--the cooperative dual task-space--which exploits the dual quaternion algebra to unify the various approaches found in the literature. The method is further extended to take into account any serially coupled kinematic chain, and a case study is performed using a simulated mobile manipulator. An original application of the cooperative dual task-space is pro- posed to intuitively represent general human-robot collaboration (HRC) tasks, and several experimentswere performed to validate the proposed techniques. Furthermore, the thesis proposes a novel class of HRC tasks wherein the robot controls all the coordination aspects; that is, in addition to controlling its own arm, the robot controls the human arm by means of functional electrical stimulation (FES). Thanks to the holistic approach developed throughout the thesis, the resultant theory is compact, uses a small set of mathematical tools, and is capable of describing and controlling a broad range of robot ma- nipulation tasks.
