Work attendance despite headache and its economic impact: a comparison between two workplaces.

Abstract: Objective.—To study work attendance despite headache in 2 different workplaces and its economic impact. Background.—Literature on the economic impact of headache traditionally has focused on direct costs. Little is known concerning headache experienced at work and its costs due to loss of effectiveness and productivity. Method.—We sent a questionnaire to 800 employees in Sweden—400 at a technology company (private employee population) and 400 at a university hospital (public employee population). We attempted to assess the prevalence of headache, work attendance despite the presence of acute headache, and the impact of acute headache upon work effectiveness. Subjects self-scored decreased work effectiveness resulting from headache during the previous 3 months and recorded the number of days at work despite headache. From these data, we estimated the economic loss resulting from headache. Results.—The survey response rate was 71.5%. The prevalence of headache was 64% in the private employee population and 78% in the public employee population. Thirty-nine percent of the private employees and 57% of the public employees reported experiencing headache as a result of stress. Fifty percent reported that they went to work despite headache, and the mean number of days at work despite headache, during the previous 3 months, was 6.6 days in the private employee group and 6.1 days in the public employee group. A 25% decrease in work effectiveness was estimated, and, extrapolating from our data, we calculated the cost of lost effectiveness due to headache among employers in Sweden to be approximately 1.4 billion euros a year. Conclusion.—The economic burden of headache experienced at work is substantial, suggesting that workplace-based treatment and prevention programs emphasizing stress management may be financially, as well as clinically, advantageous.

Method, computer program and device for determining the risk of midair collision

Abstract: A method for determining the probability of a vehicle colliding with a detected object. The object is detected. A stochastic process is determined representing a relative distance between the vehicle and the detected object. The stochastic process has a direction and a velocity relative the vehicle. A safety zone of the vehicle is defined in relation to the detected object as a straight line perpendicular to a line of sight of the detected object. The probability of colliding with the detected object over a period of time is determined as the probability of the stochastic process crossing the straight line with the direction and velocity of the stochastic process.

Plasma-enhanced active laminar flow actuator system

Abstract: The invention regards a plasma-enhanced active laminar flow actuator system (1) adapted to an aerodynamic surface (3) which has a nano- engineered composite material layer(5) comprising a set of electrodes arranged (7', 7'') in at least an upper (P1) and a lower (P2) plane extending parallel with the aerodynamic surface (3); the electrodes (7', 7'') comprising nano filaments (9); the electrodes (7') of the upper plane (P1) are arranged in the aerodynamic surface (3) such that they define a smooth and hard aerodynamic surface (3);conductors (11, 11') of nano filaments (9'') arranged for electrical communication between a control unit (13) and each of the electrodes (7', 7''), wherein the control unit (13) is adapted to address current between cooperating electrodes (7', 7'') of the upper and lower plane (P1, P2) from a current supply depending upon air flow characteristic signals fed from air flow sensor means (19).

Continuous Integration Applied to Software-Intensive Embedded Systems – Problems and Experiences

Abstract: In this paper we present a summary of factors that must be taken into account when applying continuous integration to software-intensive embedded systems. Experiences are presented from two study cases regarding seven topics: complex user scenarios, compliance to standards, long build times, many technology fields, security aspects, architectural runway and test environments. In the analysis we show how issues within these topics obstruct the organization from working according to the practices of continuous integration. The identified impediments are mapped to a list of continuous integration corner-stones proposed in literature.
