This case study describes the pregnancy of a German Shepherd bitch with a singleton (one puppy) litter as a result of early embryo resorption. Resorption was confirmed by ultrasonography and the pregnancy was regularly monitored by USG and measurements of progesterone levels until parturition. These levels stayed within the physiological range. One healthy puppy was delivered within the timeframe of a physiological pregnancy although the inner chorionic cavity diameter (ICCD) protocol used for predicting the time of parturition showed divergence from the real time of whelping.

A new type of case study, called the real-time case (RTC), was produced in the fall of 2001 and distributed via the Internet to business classes at four universities in the US and Canada. The real-time case presented the story of one company's growth and development throughout a 14-week semester. A case writer stationed full-time at the subject company published case installments weekly on the Web, allowing students to view the company-building process as it happened. The 14-week coverage of RTC enabled students to study the subject company in unprecedented depth and detail. RTC's real-time interactivity allowed students to share their analyses and best thinking with the company leadership during the company’s decision-making process.A major objective in producing the case was to heighten student engagement with the case material. To evaluate whether this objective was achieved, a survey and a focus group discussion were conducted with one of the participating MBA classes. Results from the survey and the focus group showed a high degree of engagement, plus many other benefits from the new type of case study.

This paper proposes a method of assigning trips to automated taxis (ATs) and designing the routes of those vehicles in an urban road network, and also considering the traffic congestion caused by this dynamic responsive service. The system is envisioned to provide a seamless door-to-door service within a city area for all passenger origins and destinations. An integer programming model is proposed to define the routing of the vehicles according to a profit maximization function, depending on the dynamic travel times, which varies with the ATs’ flow. This will be especially important when the number of automated vehicles (AVs) circulating on the roads is high enough that their routing will cause delays. This system should be able to serve not only the reserved travel requests, but also some real-time requests. A rolling horizon scheme is used to divide one day into several periods in which both the real-time and the booked demand will be considered together. The model was applied to the real size case study city of Delft, the Netherlands. The results allow assessing of the impact of the ATs movements on traffic congestion and the profitability of the system. From this case-study, it is possible to conclude that taking into account the effect of the vehicle flows on travel time leads to changes in the system profit, the satisfied percentage and the driving distance of the vehicles, which highlights the importance of this type of model in the assessment of the operational effects of ATs in the future.

The timely sharing and interoperation of multi-source cross-sectoral information is an important issue for a Geographic Information System (GIS). To study this issue, a real-time and open GIS model called GeoSensor is proposed in this work. GeoSensor integrates the real-time GIS model, real-time computation framework, and Open Geospatial Consortium services. This paper illustrates the system architecture and the implementation methods of the GeoSensor. One of the methods developed is the conceptual mapping of a real-time GIS data model to open GIS models and services and a real-time computation framework. The other method developed is the integration of open GIS services, a real-time computation framework, and hybrid databases. The GeoSensor was tested in a case study of building a smart river. In the case study, a comprehensive sensor web was constructed and integrated with the real-time information on rainfall, beacon, channel, sediment, and water levels derived from space-based sensors, air-borne sensors, and underground sensors from multiple sectors in the Yangtze River basin. The GeoSensor manages the comprehensive sensor web with 32 types of sensors and more than 10 billion observation records. Three application systems were developed based on the GeoSensor to manage flood control, hydropower production, and navigation of the Yangtze River. The results of the three application systems show that the real-time and open system improves the management efficiency of the Yangtze River. This system is promising for managing smart rivers.

Series of blackouts encountered in recent years in power system have been occurred because either of voltage or angle instability or both together was not detected within time and progressive voltage or angle instability further degraded the system condition, because of increase in loading. This paper presents the real-time assessment methodology of voltage stability using Phasor Measurement Unit (PMU) with observability of load buses only in power network. PMUs are placed at strategically obtained location such that minimum number of PMU’s can make all load buses observable. Data obtained by PMU’s are used for voltage stability assessment with the help of successive change in the angle of bus voltage with respect to incremental load, which is used as on-line voltage stability predictor (VSP). The real-time voltage phasors obtained by PMU’s are used as real time voltage stability indicator. The case study has been carried out on IEEE-14 bus system and IEEE-30 bus systems to demonstrate the results.

Abstract It is well known that the direct position analysis of fully-parallel manipulators provides more than one solution, i.e., more than one configuration of the mechanism is possible for a given set of the actuated variables of motion. Extra information is, thus, necessary to find the actual configuration of the manipulator. This paper presents a new algorithm for the real-time computation of the actual configuration of the generalized Stewart-Gough manipulator, also known as 6-6 fully-parallel manipulator with general geometry. The proposed algorithm makes use of two extra rotary sensors in addition to the six normally implemented in the servosystems of the manipulator. A one-to-one correspondence between the sensor measurements and the manipulator configuration is provided. With respect to other algorithms recently presented in the literature, the proposed method greatly reduces the computational burden. Finally a case study shows the effectiveness of the proposed procedure.

Study Setting

This paper introduces a management model applied to rescue a failed digital documenting services contract involving a large multinational vendor, referred to as Vendor A (VA), a large universitiy in the United States, referred to as X University (XU). The author’s objective is to tests the theory, in a case study setting, that a failed contract could be measurably salvaged through the real-time observed application of a rescue effort which emphasizes a Subordinate-Expert Empowerment (SEE) model in project rescue from its post-failure status. As a part of the literature review, an overview of project failure and varying rescue methodologies is given with an assessment of backgrounds, environments and strengths and weaknesses. Results of the study indicate the model’s ability to address the difficult issues of complex contracts by placing subordinate expertise at the forefront of dilemmas to grapple with the intricacies involved in escalated scenarios. Support of the model’s effectiveness was verified with a component listing of the resurrected project elements coupled with the survey results of all key individuals of the rescue process.
