Non-fragile sliding mode control for flexible air-breathing hypersonic vehicles
2012
The non-fragile sliding mode tracking control design problem for a flexible air-breathing hypersonic vehicles (FAHVs) is investigated in this paper. A linearized model is constructed with respect to a trim point for the nonlinear, dynamically coupled simulation model of the FAHVs with external disturbance, then a reference model is designed and a tracking error model is proposed. An integral sliding surface is designed, and then the non-fragile H ∞ controller design problem for the sliding mode dynamics is discussed. sufficient condition is derived for the existence of such a controller in the presence of unmatched disturbance. A SMC law is derived to guarantee the reachability of the speci…
Network Slicing Enabled Resource Management for Service-Oriented Ultra-Reliable and Low-Latency Vehicular Networks
2020
Network slicing has been considered as a promising candidate to provide customized services for vehicular applications that have extremely high requirements of latency and reliability. However, the high mobility of vehicles poses significant challenges to resource management in such a stochastic vehicular environment with time-varying service demands. In this paper, we develop an online network slicing scheduling strategy for joint resource block (RB) allocation and power control in vehicular networks. The long-term time-averaged total system capacity is maximized while guaranteeing strict ultra-reliable and low-latency requirements of vehicle communication links, subject to stability const…

Thermal-Infrared Spectral and Angular Characterization of Crude Oil and Seawater Emissivities for Oil Slick Identification
2014
Previous work has shown that the emissivity of crude oil is lower than that of the seawater in the thermal-infrared (TIR) spectrum. Thus, oil slicks cause an emissivity decrease relative to the seawater in that region. The aim of this paper was to carry out experimental measurements to characterize the spectral and angular variations of crude oil and seawater emissivities. The results showed that the crude oil emissivity is lower than the seawater emissivity and that it is essentially flat in the atmospheric window of 8-13 μm. The crude oil emissivity has a marked emissivity decrease with the angle (from 0.956 ± 0.005 at 15 ° to 0.873 ± 0.007 at 65 °), which is even higher than that of the …
Iekštelpu vides kvalitātes novērtējums pirmsskolas un skolas vecuma bērnu izglītības iestādēs
2017
Bakalaura darba “Iekštelpu vides kvalitātes novērtējums pirmsskolas un skolas vecuma bērnu izglītības iestādēs” ietvaros veikts iekštelpu mikroklimata un piesārņojuma līmeņa novērtējums trīs izglītības iestādēs (PII Rīgas Valdorfskolas bērnudārzs, Rīgas Valdorfskolā un Rīgas 49. vidusskolā) laika posmā no 2016. gada rudens līdz 2017. gada pavasarim. Novērtēšana veikta izmantojot tiešo mērījumu metodi, atsevišķu parametru atbilstība vērtēta salīdzinājumā ar noteiktajiem normatīvajiem lielumiem, savukārt citi, kuriem normatīvu nav, salīdzināti ar Pasaules veselības organizācijas vadlīnijās iekļautajiem lielumiem.

Der, die oder das Nutella : die Verwendung des Genus in Produktnamen
2017
Saksan kielessä substantiiveilla on suku. Se on joko feminiini, maskuliini tai neutri. Aina ei kuitenkaan tiedetä, mikä suku substantiivilla on. Esimerkiksi monista vierassanoista, eli alkuperältään toisen kielen kuin saksan sanoista tai tuotenimistä sukua ei aina tiedetä varmasti. Vierassanoilla on erilaisia suvun määräytymisen periaatteita ja samat periaatteet pätevät myös tuotenimien kanssa. Tässä kandidaatin tutkielmassa perehdytään Nutella- tuotenimen suvun määräytymiseen. Tutkielmassa selvitettiin, mikä suku on yleisimmin käytetty ja onko saksankielisten maiden välillä eroja käytön suhteen. Tutkimuksessa käytettiin DeReKo-Korpusta, joka sisältää saksalaisia, itävaltalaisia, sveitsiläi…

Supporting Impact Analysis by Program Dependence Graph Based Forward Slicing
2007
Since software must evolve to meet the typically changing requirements, source code modifications can not be avoided. Impact analysis is one of the central and relatively demanding tasks of software maintenance. It is constantly needed while aiming at ensuring the correctness of the made modifications. Due to its importance and challenging nature automated support techniques are required. Theoretically, forward slicing is a very suitable technique for that purpose. Therefore, we have implemented a program dependence graph (PDG) based tool, called GRACE, for it. For example, due to the typical rewritings of Visual Basic programs there is a great need to support their impact analysis. However…
