Solving the length constrained K-drones rural postman problem

2021

[EN] In this paper we address the Length Constrained K-Drones Rural Postman Problem (LC K-DRPP). This is a continuous optimization problem where a fleet of homogeneous drones have to jointly service (traverse) a set of (curved or straight) lines of a network. Unlike the vehicles in classical arc routing problems, a drone can enter a line through any of its points, service a portion of that line, exit through another of its points, then travel directly to any point on another line, and so on. Moreover, since the range of the drones is restricted, the length of each route is limited by a maximum distance. Some applications for drone arc routing problems include inspection of pipelines, railwa…

Artilleriâ Velikogo Knâžestva Litovskogo v XVII v. : finansirovanie, voennye transportnye rashody, remeslennaâ rabota

2015

State artillery in Lithuania in the seventeenth century was relatively neglected area of military and only from 1637 years it constituted a separate body. In the second half of the seventeenth century cannon in the arsenals of Lithuania were outdated and there were rarely works with new ones. During this period, it also struggled with the problem of its unification. In the Grand Duchy of Lithuania there was also a private artillery, and the law allowed anyone nobleman, if he could afford it, to have a cannon. The private fortresses they were much more modern than the artillery State. Another issue was transporting artillery to the war,which was associated with the employment of many people,…

Atbildība par nelikumīgām darbībām sportā

2019

Šī darba temats ir atbildība par nelikumīgām darbībām sportā, konkrētāk, par manipulācijām ar sporta sacensībām un antidopinga noteikumu pārkāpumiem, skatoties uz faktu, ka par pirmo Krimināllikumā iekļauts atsevišķs pants, bet par dopinga lietošanu nav un kriminālatbildību iespējams piemērot tikai ļoti retos gadījumos. Tālākai tēmas analīzei būtiski izprast jēdzienu saturu, šo darbību praktisko izpausmi un ietekmi uz sportistu tiesībām, interesēm, kā arī uz sabiedrību kopumā. Bakalaura darba mērķis ir apskatīt minēto neatļauto rīcību aktualitāti Latvijā, regulējumu un tā atbilstību starptautiskajiem tiesību aktiem, kā arī regulējumu ārvalstīs, kurās par manipulācijām ar sporta sacensībām u…

Examining the effect of adverse weather on road transportation using weather and traffic sensors.

2018

Adverse weather related to reduced visibility caused by fog and rain can seriously affect the mobility and safety of drivers. It is meaningful to develop effective intelligent transportation system (ITS) strategies to mitigate the negative effects of these different types of adverse weather related to reduced visibility by investigating the effect of rain and fog on traffic parameters. A number of previous researches focused on analyzing the effect of adverse weather related to reduced visibility by using simulated traffic and weather data. There are few researchers that addressed the impact of adverse weather instances using real-time data. Moreover, this paper conducts comprehensive inves…

Destination Attractiveness Drivers among Urban Hostel Tourists: An Analysis of Frustrators and Delighters

2015

This study is based on data from 679 tourists staying at hostel accommodation facilities in Zagreb, a propulsive city-break destination in Central Europe. Besides providing insight into the socio-demographic and behavioural characteristics of hostel tourists, this study uncovers determinant destination attributes influencing their perceptions of destination attractiveness. In particular, impact asymmetry analysis identified potential sources of delight and frustration among hostel tourists. Since the hostel tourist segment, as such, is almost completely unconsidered in contemporary tourism research, partly covered only by a few studies on youth travellers and backpackers, the results of thi…

Factors influencing sports achievement of bobsleigh in the second phase of Covid-19 crisis

2022

Covid-19 krīzes periodā novērojot un analizējot izmaiņas Latvijas, Vācijas un Austrijas bobsleja U23 grupas komandu darbībā, tika realizēts pētījums “Bobsleja sporta sasniegumu ietekmējošie faktori Covid-19 krīzes otrajā posmā”. To veido vairāku pētnieku teorētiskās atziņas par sportošanas motivāciju, pieredzi, faktoriem, kas to ietekmē un izsauc nopietnas izmaiņas ikdienā un sporta karjerā. Pētījuma mērķis – noskaidrot, kā vīrusa Covid-19 pandēmijas apstākļos izmainījās Latvijas, Vācijas un Austrijas bobslejistu sportošanas motivācija. Pētījuma otrajā daļā ar aptaujas metodes palīdzību noskaidrots, kā Covid-19 karantīnas apstākļi ir ietekmējuši Latvijas, Vācijas un Austrijas bobsleja U23 g…

Assessing the electricity consumption of outdoor lighting systems in the presence of automatic control: The OL-BAC factors method

2020

Abstract Building automation systems are able to influence significantly buildings’ energy performance. The BAC factors method, presented for the first time by the International Standard EN 15232, is the most used and simple instrument for evaluating the impact of such systems in terms of reduction of the electrical and thermal energy consumption of buildings services. Nevertheless, Standard EN 15232 does not take into consideration the automation of lighting systems serving buildings’ external areas like passages, gardens, entrance walkways, etc. In some cases, such areas can be very extended and, as a consequence, responsible for a not negligible percentage of the overall electricity cons…

Application of Radio Environment Map Reconstruction Techniques to Platoon-based Cellular V2X Communications

2020

Vehicle platoons involve groups of vehicles travelling together at a constant inter-vehicle distance, with different common benefits such as increasing road efficiency and fuel saving. Vehicle platooning requires highly reliable wireless communications to keep the group structure and carry out coordinated maneuvers in a safe manner. Focusing on infrastructure-assisted cellular vehicle to anything (V2X) communications, the amount of control information to be exchanged between each platoon vehicle and the base station is a critical factor affecting the communication latency. This paper exploits the particular structure and characteristics of platooning to decrease the control information exch…

Multidimensional prediction of work traffic crashes among Spanish professional drivers in cargo and passenger transportation

2020

The aim of this study was to examine the effect of different environmental, mechanical and individual factors associated with fatalities and serious injuries caused by work traffic accidents among cargo and passenger transport drivers (CPTD) in Spain. For this cross-sectional study, national data on work traffic accidents collected in Spain during the last 3 years were analyzed through a regression modeling approach, in order to predict the severity of traffic crashes involving CPTD. Using binary logistic regression analyses, it was found that the type of road and accident, the meteorological, light and vehicle conditions, individual characteristics and risky driving behaviors significantly…
