Accelerating short read mapping on an FPGA (abstract only)

2012

The explosive growth of short read datasets produced by high throughput DNA sequencing technologies poses a challenge to the mapping of short reads to a reference genome in terms of sensitivity and execution speed. Existing methods often use a restrictive error model for computing the alignments to improve speed, whereas more flexible error models are generally too slow for large-scale applications. Although a number of short read mapping software tools have been proposed, designs based on hardware are relatively rare. In this paper, we present a hybrid system for short read mapping utilizing both software and field programmable gate array (FPGA)-based hardware. The compute intensive semi-g…

Carbon sequestration in French agricultural soils: A spatial economic evaluation

2021

International audience; Soil organic carbon sequestration measures entail costs to farmers with different individual characteristics and located in different areas. A cost‐effective analysis taking into account these heterogeneities is crucial for developing effective public policy aimed at increasing carbon sequestration. We undertake such an analysis focusing on three soil organic carbon sequestration measures: no‐till, extension of temporary grasslands, and hedgerows. Through an optimization model applied to France, our results show that only extension of temporary grasslands can store carbon at low cost, though their potential for carbon sequestration is also low. For an ambitious carbo…

Likviditātes vadības politika Eirosistēmā

2018

Tradicionālo monetārās politikas instrumentu izmantošana pierādījās nepietiekami efektīva globālās finanšu krīzes radīto ārkārtējo apstākļu uzlabošanai, tāpēc Eiropas Centrālā banka no 2007. gada sāka izmantot nestandarta monetārās politikas metodes, lai stabilizētu situāciju finanšu tirgos. No 2009. gada Eiropas Centrālā banka sāka izmantot aktīvu pirkšanas programmas funkcionalitātes nodrošināšanai noteiktos finanšu tirgus segmentos, monetārās politikas transmisijas veicināšanai, kopš 2015. gada ar mērķi veicināt ekonomisko aktivitāti un pacelt inflācijas līmeni līdz noteiktajam mērķim “tuvu, bet zem 2%” vidējā termiņā. Pētījuma mērķis ir, novērtējot ECB likviditātes vadības politiku, tās…

Eiropas Savienības fondu finansējuma programmu darbība

2015

Diplomdarba galvenais mērķis ir izpētīt ES fondu 2007.–2013. gada plānošanas perioda 3 darbības programmu īstenošanu Latvijā, tās ietekmējošos faktorus un izstrādāt priekšlikumus 2014–2020. gada perioda programmas finansējuma apguves efektivitātes palielināšanai. Izvēlētā tēma ir aktuāla, jo 2007.-2013.gada ES fondu investīciju periods ir nonācis noslēguma fāzē un ir būtiski veikt nepieciešamos secinājumus, lai nākamā ES finansējuma perioda līdzekļi tiktu apgūti vēl produktīvāk. Darba pirmajā daļā uzmanība tiek pievērsta investīciju jēdzienam un tā būtībai. Darba otrajā daļa autos analizē ES fondu darbības programmu „Cilvēkresursi un nodarbinātība”, „Uzņēmējdarbība un inovācijas” un „Infras…

Experimental Validation of a Novel Method for Harmonic Mitigation for a Three-Phase Five-Level Cascaded H-Bridges Inverter

2019

In modern high-power electrical drives, the efficiency of the system is a crucial constraint. Moreover, the efficiency of power converters plays a fundamental role in modern applications requiring also a limited weight, such as the electric vehicles and novel more electric aircraft. The reduction of losses pushes for systems with a dc bus and a high number of dc/ac converters, widespread in the vehicle, not burdened by a too expensive data processing system. The purpose of this article is to concur to reduce losses by proposing an innovative selective harmonic mitigation method based on the identification of the working areas where the reference harmonics present lower amplitudes. In partic…

A new Diagnostic and Protective System (DPS) suitable for wheelchair electrical drive applications has been prepared. Such a system is able to perform both monitoring and long-distance transmission of key signals that are used as pre-fault and fault indicators. The system, moreover, may detect several anomalous working conditions by means of reliable diagnosis procedures and carries out actions to protect the electrical drive and to drive the disabled people in safe conditions. In particular the design, the realization and the performance analysis of the new dedicated diagnostic system, which exploits a programmable logic controller (PLC) as DRS hardware, are described and discussed. The ef…

Real-Time Localization of Epileptogenic Foci EEG Signals: An FPGA-Based Implementation

2020

The epileptogenic focus is a brain area that may be surgically removed to control of epileptic seizures. Locating it is an essential and crucial step prior to the surgical treatment. However, given the difficulty of determining the localization of this brain region responsible of the initial seizure discharge, many works have proposed machine learning methods for the automatic classification of focal and non-focal electroencephalographic (EEG) signals. These works use automatic classification as an analysis tool for helping neurosurgeons to identify focal areas off-line, out of surgery, during the processing of the huge amount of information collected during several days of patient monitori…

An AER handshake-less modular infrastructure PCB with x8 2.5Gbps LVDS serial links

2014

Nowadays spike-based brain processing emulation is taking off. Several EU and others worldwide projects are demonstrating this, like SpiNNaker, BrainScaleS, FACETS, or NeuroGrid. The larger the brain process emulation on silicon is, the higher the communication performance of the hosting platforms has to be. Many times the bottleneck of these system implementations is not on the performance inside a chip or a board, but in the communication between boards. This paper describes a novel modular Address-Event-Representation (AER) FPGA-based (Spartan6) infrastructure PCB (the AER-Node board) with 2.5Gbps LVDS high speed serial links over SATA cables that offers a peak performance of 32-bit 62.5…
