CUDA-BLASTP: Accelerating BLASTP on CUDA-enabled graphics hardware
2011
Scanning protein sequence database is an often repeated task in computational biology and bioinformatics. However, scanning large protein databases, such as GenBank, with popular tools such as BLASTP requires long runtimes on sequential architectures. Due to the continuing rapid growth of sequence databases, there is a high demand to accelerate this task. In this paper, we demonstrate how GPUs, powered by the Compute Unified Device Architecture (CUDA), can be used as an efficient computational platform to accelerate the BLASTP algorithm. In order to exploit the GPU's capabilities for accelerating BLASTP, we have used a compressed deterministic finite state automaton for hit detection as wel…
Latency-Oblivious Distributed Task Scheduling for Mobile Edge Computing
2018
Mobile Edge Computing (MEC) is emerging as one of the effective platforms for offloading the resource- and latency-constrained computational services of modern mobile applications. For latency- and resource-constrained mobile devices, the important issues include: 1) minimize end-to-end service latency; 2) minimize service completion time; 3) high quality-of-service (QoS) requirement to offload the complex computational services. To address the above issues, a latencyoblivious distributed task scheduling scheme is designed in this work to maximize the QoS performance and goodput for the MEC services. Unlike most of the existing works, we consider the latency-oblivious property of different …
Improvement of the expression of upper limb muscle strength and balance in a group of patients with multiple sclerosis, through a proprioceptive reha…
2022
In multiple sclerosis (MS) patients, symptoms such as: fatigue, lack of physical energy, spasticity, difficulty in performing movements, and motor coordination disorders, and with tremors, dizziness and postural instability are among the most common complications. Cattaneo et al. (2007) studied the effects of stability training on MS patients and described it as an effective intervention in reducing falls risk, improving stability, and strength. Therefore, the present study aimed to confirm early observations by the application of a proprioceptive rehabilitation program targeting balance and strength on MS patients. 13 subjects with MS, 5 male and 8 female, volunteered in the study. A MAP h…
Immuno-MALDI-MS in Human Plasma and on-Chip Biomarker Characterizations at the Femtomole Level
2012
Immuno-SPR-MS is the combination of immuno-sensors in biochip format with mass spectrometry. This association of instrumentation allows the detection and the quantification of proteins of interest by SPR and their molecular characterization by additional MS analysis. However, two major bottlenecks must be overcome for a wide diffusion of the SPR-MS analytical platform: (i) To warrant all the potentialities of MS, an enzymatic digestion step must be developed taking into account the spot formats on the biochip and (ii) the biological relevancy of such an analytical solution requires that biosensing must be performed in complex media. In this study, we developed a procedure for the detection …
Estudio volumétrico de la cresta ósea infracigomática mediante tomografía computarizada de haz cónico

Birefringent porous silicon membranes for optical sensing
2012
In this work anisotropic porous silicon is investigated as a material for optical sensing. Birefringence and sensitivity of the anisotropic porous silicon membranes are thoroughly studied in the framework of Bruggeman model which is extended to incorporate the influence of environment effects, such as silicon oxidation. The membranes were also characterized optically demonstrating sensitivity as high as 1245 nm/RIU at 1500 nm. This experimental value only agrees with the theory when it takes into consideration the effect of silicon oxidation. Furthermore we demonstrate that oxidized porous silicon membranes have optical parameters with long term stability. Finally, we developed a new model …
Tietotekniikan valtakunnallisten oppisisältöjen toteutuminen Keski-Suomen peruskoulujen opetuskäytänteissä
2017
Tutkimus sai alkunsa kiinnostuksesta uusia Perusopetuksen opetussuunnitelman perusteita kohtaan. Vuonna 2014 hyväksytty POPS asettui erityisesti tieto- ja viestintätekniikan opetuksen osalta vastaamaan perusopetuksessa havaittuihin puutteisiin ja ongelmiin. Tutkimuksen tarkoituksena oli selvittää mitä uusia sisältöjä POPS14 tuo tietotekniikan opetukseen sekä kuinka noiden sisältöjen opetus toteutuu koulujen arjessa. Tutkimuksessa tunnistettiin tyypilliset ja yleisesti käytössä olevat TVT:n opetusmenetelmät ja niitä pyrittiin kuvailemaan laadullisen tutkimuksen keinoin. Tavoitteeseen päästiin lähinnä Opetushallituksen julkaisuihin kohdistuneen kirjallisuuskatsauksen, Keski-Suomen peruskouluj…
An Efficient Implementation of Parallel Parametric HRTF Models for Binaural Sound Synthesis in Mobile Multimedia
2020
The extended use of mobile multimedia devices in applications like gaming, 3D video and audio reproduction, immersive teleconferencing, or virtual and augmented reality, is demanding efficient algorithms and methodologies. All these applications require real-time spatial audio engines with the capability of dealing with intensive signal processing operations while facing a number of constraints related to computational cost, latency and energy consumption. Most mobile multimedia devices include a Graphics Processing Unit (GPU) that is primarily used to accelerate video processing tasks, providing high computational capabilities due to its inherent parallel architecture. This paper describes…
Consumer adoption of mobile technologies: a literature review
2015
Although the total number of mobile subscriptions reached 6.8 billion worldwide (ITU, 2013) confirming in the process that mobile technology is widespread, academic literature has so far focused only on explaining adoption of mobile technology and services. This literature review analyses 67 studies from the period 2005-2013 and finds the following: a) most studies are quantitative in nature and come from Asia; b) the Technology Acceptance Model is the most used theory; c) future research should also utilise qualitative methods and examine the behavioural outcomes of mobile adoption instead of simply adoption in consumer markets. peerReviewed
The feasibility of working memory tablet tasks in predicting scholastic skills in classroom settings
2019
Cognitive assessment in natural group settings facilitates data collection but poses threats to the validity. In this study, tablet‐based working memory (WM) tasks, the counting span, and reading span were used in predicting 12‐year‐old children's (N = 837) scholastic skills and fluid intelligence in a classroom with environmental noise. WM tasks had excellent internal consistency, correlated with scholastic skills, and accounted for more of the variance in cognitive performance (grade point average, fluid intelligence, scholastic skills) compared with individually administered (n = 190) digit span task. Furthermore, the multilevel analysis revealed that compared with the classrooms with no…
