  1. 1. Probabilistic and Experimental Analysis of Heuristic Algorithms for the Multiple-Depot Vehicle-Routing Problem

    Författare :Libertad Tansini; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; probabilistic analysis; Multi-Depot Vehicle-Routing problem; heuristics; Time-Windows;

    Sammanfattning : The aim of this thesis is to analyze different heuristic algorithms for solving the Multi-Depot Vehicle-Routing problem (MDVRP) with k depots and n points to be serviced (customers). The objective is to produce a set of service routes which minimizes the total distance traveled. Heuristic approaches are essential since the problem is NP-hard. LÄS MER

  2. 2. Zur Getrennt‑, Zusammen‑ und Bindestrichschreibung von Substantivkomposita im Deutschen (1550–1710)

    Författare :Daniel Solling; Bo Andersson; Bettina Jobin; Claudine Moulin; Uppsala universitet; []
    Nyckelord :HUMANIORA; HUMANITIES; open compound nouns; closed compound nouns; hyphenation; compound nouns; Early New High German; historical graphematics; historical graphemics; orthography; Getrenntschreibung; Zusammenschreibung; Bindestrichschreibung; Substantivkomposita; Frühneuhochdeutsch; historische Graphematik; historische Graphemik; Orthographie; German; Tyska;

    Sammanfattning : This thesis investigates the changes in whether compound nouns were closed (written as one word), open (written as separate words) or hyphenated in Early New High German between 1550 and 1710. Due to the fact that there were no orthographic norms in the German of this time, graphematic phenomena in this period of the German language are very fruitful to examine. LÄS MER

  3. 3. Optimal Truck Scheduling : Mathematical Modeling and Solution by the Column Generation Principle

    Författare :Myrna Palmgren; Torbjörn Larsson; Niklas Kohl; Linköpings universitet; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; optimisation; pickup and delivery problem; transportation; scheduling; column generation; integer programming; MATHEMATICS; MATEMATIK;

    Sammanfattning : We consider the daily transportation problem in forestry which arises when transporting logs from forest sites to customers such as sawmills and pulp and paper mills. Each customer requires a specific amount of a certain assortment, and the deliveries to the customers can be made within time intervals, known as time windows. LÄS MER

  4. 4. Environmental Pesticide Exposure and Neurobehavioral Effects among Children of Nicaraguan Agricultural Workers

    Författare :Teresa Rodríguez; Catharina Wesseling; Ingvar Lundberg; Berna van Wendel de Joode; Ingvar Bergdahl; Uppsala universitet; []
    Nyckelord :pesticides; organophosphates; pyrethroids; children; cognitive function; behavioral outcomes; neurodevelopment; Occupational and Environmental Medicine; Arbets- och miljömedicin; Epidemiologi; Epidemiology;

    Sammanfattning : Background: Children exposed to pesticides are susceptible for neurodevelopmental disruption. Data from developing countries are scarce.Aim: Assessing long-term and recent pesticide exposure in Nicaraguan children in relation to parental pesticide use and examining potential associated neurobehavioral effects.

  5. 5. Planning and evaluation of autonomous vehicles in freight and public transport services

    Författare :Wei Zhang; Erik Jenelius; Hugo Badia; Miquel Estrada; KTH; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY;

    Sammanfattning : The introduction of automation technology in transport systems brings both opportunities and challenges. The direct benefits of automation technology are obvious, for instance, reduced marginal driving cost, improved energy efficiency and increased safety. LÄS MER
