Vertical Line Array (VLA) Beam - Forming Algorithm with constant beam width.

2005

The algorithm proposed is a beam-forming algorithm. Many beam-steering and beam-forming algorithms exist and they are all based on the control of delay times between the signals driving the loudspeakers of the line array; this kind of control produces a variable beam-width depending on steering angle and frequency. In our case beam width doesn't depend on frequency and steering angle because a specific beam forming technique was applied by shading the amplitudes of signals for each element of the array according to the frequency applied. Furthermore a weighting function was utilized for spatial windowing. Spatial windowing allows reduction of secondary lobes without varying the directivity …

User behaviours after critical mobile application incidents : the relationship with situational context

2017

Users occasionally have critical incidents with information systems (IS). A critical IS incident is an IS product or service experience that a user considers to be unusually positive or negative. Critical IS incidents are highly influential in terms of users’ overall perceptions and customer relationships; thus, they are crucial for IS product and service providers. Therefore, it is important to study user behaviors after such incidents. Within IS, the relationships between the situational context and user behaviors after critical incidents have not been addressed at all. Prior studies on general mobile use as a related research area have recognized the influence of the situational context,…

User Expressions Translated into Requirements

2010

Grounding the development of mobile and ubiquitous services on actual needs and behaviors of users, rather than on designers’ intuition, is a well-established tradition. However, gathering data about users in different contexts usually results in large amounts of data that have to be analyzed and translated into requirements. This crucial activity and its outcome are often shaped by the preconceptions of the developers or researchers. Despite this subjectivity, the translation process is seldom transparent. The aim of this paper, therefore, is to contribute to the field by presenting a process for translating user expressions into needs and later into requirements using Reiss’ taxonomy of h…

Effects of Personal Traits on Generation Y Consumers' Attitudes Toward the Use of Mobile Devices for Communication and Commerce

2012

The purpose of this study was to investigate the effects of young adult consumers’ personal traits (high-tech involvement, experiment proclivity, and fashion/brand leadership) on their perceptions of and attitudes toward using mobile devices for communications and commerce. The integrated stimulus-organism-responses paradigm (Fiore & Kim, 2007) served as the overarching framework, combining the uses and gratifications theory (Blumler & Katz, 1974) and the extended technology acceptance model (Kim, Ma, & Park, 2009). A convenience sample of 504 college students in 2 U. S. universities provided usable responses to our survey. Causal modeling analysis results showed that personal trait varia…

Zināšanu pārbaudes testi izmantošanai viedierīcēs

2018

Diplomdarbā aprakstītā pētījuma mērķis izpētīt mobilo testu izmantošanas aktualitāti un pielietošanas iespējas, lai veicinātu to izmantošanu pedagoģiskajā procesā. Pētījumam izmantoto datu ieguves kvalitatīvās metodes ir intervijas un platformu analīze, kvantitatīvā - pedagogu aptauja. Interviju respondenti ir sākumskolas, vidusskolas un augstskolas pedagogi, kā arī Uzdevumi.lv direktors Edgars Škutāns. Tika vadīts seminārs, iepazīstinot profesionālās vidusskolas Mediju mākslas nodaļas pedagogus ar zināšanu pārbaudes testu platformu QUIZIZZ, pēc kura tika veikta pedagogu aptauja. Pētījumā noskaidrots, ka viedierīcērs izmantojamo zināšanu pārbaudes testu galvenās priekšrocības ir automātiska…

Mobilie līdzekļi skolēnu vārdu krājuma paplašināšanai pamatskolas angļu valodas stundās

2018

Viedtālruņu pastāvīgā klātbūtne pamatskolas skolēnu dzīvē un mobilo mācību līdzekļu strauja attīstība ir pamats idejai par to apvienošanu, lai iepazīstinātu skolēnus ar jauniem motivējošiem vārdu krājuma apguves veidiem. Atsevišķa gadījuma pētījums tika veikts Teteles pamatskolā. Kā datu iegūšanas metodes tika izmantotas skolotāju aptaujas, intervijas ar angļu valodas skolotājiem, 57 skolēnu aptaujas (vecumā no 10 līdz 14 gadiem) pirms pētījuma, mobilo līdzekļu praktiskā izmantošana, un pamatskolas vecuma skolēnu aptaujas pēc pētījuma. Izmantojot pētījumā iegūtos datus, Diplomdarba autors sasniedza mērķi izstrādāt vadlīnijas skolotājiem, kuri vēlās izvairīties no jebkādām iespējamām grūtībā…

Stages of Exercise Behavior Change in a Digital Wellness Program for Aged People : Relationship With Self-Efficacy for Exercise

2022

Sustained physical activity and exercise are central to healthy ageing. Yet, the majority of aged people are insufficiently physically active. Digital wellness technologies are potential in promoting exercise behaviors among aged people, but more detailed research on their potential to promote behavior change is limited. To address this gap, the purpose is to investigate how partaking in a digital wellness program influences the stage of exercise behavior change among aged people and to test whether self-efficacy for exercise can differentiate the program participants in terms of the stages of change. The investigation builds on the stages of exercise behavior change derived from the transt…

The New Media and Heterotopic Technologies in the Philippines

2008

Information overload is perhaps the most common frustration of our age. It strikes everyone: young and old, educated and uneducated, rich and poor, first world and third world. Human communication has taken on the qualities of the supernatural. Indeed it has surpassed it! Zeus could only rely on Mercury’s speed to convey his commands; presently electronic messages zip around the globe and the universe at the speed of light. No wonder that new communication technologies often evoke notions of the supernatural. This paper deals with some of the unexpected effects of the new communication technologies, in particular for mobile phones. While the mobile has become the icon of connectedness, it a…
