  1. 1. Commuting time choice and the value of travel time

    Författare :Jan-Erik Swärdh; Lars Hultkrantz; Bruno De Borger; Örebro universitet; []
    Nyckelord :SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; Value of time; Value of travel time; Commuting; Commuting time changes; Value of commuting time; Register data; On-the-job search; Revealed preferences; Stated preferences; Hypothetical bias; Scheduling constraints; Relocations; Certainty calibration; Quantile regression; Mixed logit; Gender differences; Economics; Nationalekonomi; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; Economics; Nationalekonomi;

    Sammanfattning : In the modern industrialized society, a long commuting time is becoming more and more common. However, commuting results in a number of different costs, for example, external costs such as congestion and pollution as well as internal costs such as individual time consumption. LÄS MER

  2. 2. Real-Time Workload Models : Expressiveness vs. Analysis Efficiency

    Författare :Martin Stigge; Wang Yi; Sanjoy Baruah; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Real-time systems; task models; EDF; fixed-priority scheduling; schedulability analysis; response-time analysis; abstraction refinement; Datavetenskap med inriktning mot realtidssystem; Computer Science with specialization in Real Time Systems;

    Sammanfattning : The requirements for real-time systems in safety-critical applications typically contain strict timing constraints. The design of such a system must be subject to extensive validation to guarantee that critical timing constraints will never be violated while the system operates. LÄS MER

  3. 3. Servicescapes seen by visually impaired travellers : Time-geography approach to servicescape research

    Författare :Alma Raissova; Institutionen för service management och tjänstevetenskap; []
    Nyckelord :SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; SAMHÄLLSVETENSKAP; SOCIAL SCIENCES; servicescape; time-geography; constraints; tactics; blind; visually impaired persons; servicescape; tidsgeografi; begränsningar; taktik; blinda; synskadade;

    Sammanfattning : Knowledge gaps remain in the study of servicescapes, since existing research on servicescapes tends to ignore major advances in the understanding of space and time as social phenomena. One aspect that particularly requires further study is how emerging constraints influence customers’ interactions with organized service places. LÄS MER

  4. 4. Issues in Urban Travel Demand Modelling : ICT Implications and Trip timing choice

    Författare :Maria Börjesson; Staffan Algers; Kay Axhausen; KTH; []
    Nyckelord :ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; Journey; Mathematical model; Origin traffic ; Time; Telecommuting; Journey time; Variability; Stated preference; Delay; Civil engineering and architecture; Samhällsbyggnadsteknik och arkitektur; 11 Road: Personal transport; 11 Road: Personal transport; Travel Demand; ICT; Tele-substitution; Revealed Preference; Stated Preference; Mixed Logit; Unobserved Heterogeneity; Travel Time Uncertainty; Schedule Delay;

    Sammanfattning : Travel demand forecasting is essential for many decisions, such as infrastructure investments and policy measures. Traditionally travel demand modelling has considered trip frequency, mode, destination and route choice. This thesis considers two other choice dimensions, hypothesised to have implications for travel demand forecasting. LÄS MER

  5. 5. Symmetry Breaking Ordering Constraints

    Författare :Zeynep Kiziltan; Andreas Hamfelt; Toby Walsh; Pedro Meseguer; Uppsala universitet; []
    Nyckelord :NATURAL SCIENCES; NATURVETENSKAP; NATURVETENSKAP; NATURAL SCIENCES; Datavetenskap; Constraint satisfaction; constraint programming; modelling; symmetry breaking; global constraints; Datavetenskap; Computer science; Datavetenskap;

    Sammanfattning : Many problems in business, industry, and academia can be modelled as constraint programs consisting of matrices of decision variables. Such “matrix models” often have symmetry. In particular, they often have row and column symmetry as the rows and columns can freely be permuted without affecting the satisfiability of assignments. LÄS MER
