Towards a Versatile Problem Diagnosis Infrastructure for LargeWireless Sensor Networks

In this position paper, we address the issue of durable maintenance of a wireless sensor network, which will be crucial if the vision of large, long-lived sensornets is to become reality. Durable maintenance requires tools for diagnosing and fixing occurring problems, which can range from internode connectivity losses, to time synchronization problems, to software bugs. While there are solutions for fixing problems, an appropriate diagnostic infrastructure is essentially still lacking. We argue that diagnosing a sensornet application requires the ability to dynamically and temporarily extend the application on a selected group of nodes with virtually any functionality. We motivate this claim based on deployment experiences to date and propose a highly nonintrusive solution to dynamically extending a running application on a resource-constrained sensor node

Information on antiprotonic atoms and the nuclear periphery from the PS209 experiment

In the PS209 experiments at CERN two kinds of measurements were performed: the in-beam measurement of X-rays from antiprotonic atoms and the radiochemical, off-line determination of the yield of annihilation products with mass number A_t -1 (less by 1 than the target mass). Both methods give observables which allows to study the peripheral matter density composition and distribution.Comment: LaTeX (espcrc1 style), 6 pages, 3 EPS figures, 1 table, Proceedings of the Sixth Biennal Conference on Low-Energy Antiproton Physics LEAP 2000, Venice, Ital

Coulomb excitation of 68^{68}Ni at safe energies

The $B(E2;0^+\to2^+)$ value in $^{68}$Ni has been measured using Coulomb excitation at safe energies. The $^{68}$Ni radioactive beam was post-accelerated at the ISOLDE facility (CERN) to 2.9 MeV/u. The emitted $\gamma$ rays were detected by the MINIBALL detector array. A kinematic particle reconstruction was performed in order to increase the measured c.m. angular range of the excitation cross section. The obtained value of 2.8$^{+1.2}_{-1.0}$ 10$^2$ e$^2$fm$^4$ is in good agreement with the value measured at intermediate energy Coulomb excitation, confirming the low $0^+\to2^+$ transition probability.Comment: 4 pages, 5 figure

“NOT MUCH OF A JOB”: EVERYDAY LIFE AND LABOR AT CAMP AU TRAIN

In this thesis, I use data from Camp Au Train, a Civilian Conservation Corp camp in Michigan’s Hiawatha National Forest, as a case study to connect the everyday life of enrollees with dominant government narratives while including a focus on labor and the capitalist crisis of the Great Depression. Using the vantage point of work, play, study, and health, I integrate archaeological, historic, and photographic evidence to show contradictions between the enrollees’ real lived experience and the dominant perspectives of the CCC ‘authorities’ who organized their lives. I argue that to interpret these contradictions, the CCC needs to be connected to the larger context of labor and capitalism. These insights are crucial for understanding contemporary calls for a New New Deal to address men’s lost jobs and the ‘crisis of masculinity’ in order to make meaningful changes toward solving these real problems for the future

"Safe" Coulomb Excitation of 30Mg

We report on the first radioactive beam experiment performed at the recently commissioned REX-ISOLDE facility at CERN in conjunction with the highly efficient gamma spectrometer MINIBALL. Using 30Mg ions accelerated to an energy of 2.25 MeV/u together with a thin nat-Ni target, Coulomb excitation of the first excited 2+ states of the projectile and target nuclei well below the Coulomb barrier was observed. From the measured relative de-excitation gamma ray yields the B(E2; 0+ -> 2+) value of 30Mg was determined to be 241(31) e2fm4. Our result is lower than values obtained at projectile fragmentation facilities using the intermediate-energy Coulomb excitation method, and confirms the theoretical conjecture that the neutron-rich magnesium isotope 30Mg lies still outside the ``island of inversion''

Potential of city break clubbing tourism in Wrocław

Over the last decade Polish cities have become popular destinations of the foreign clubbing tourism. Interest of foreign tourists, however, is not reflected in the interest of scientists, because clubbing tourism-related issues have not been extensively studied in the literature regarding Polish cities. In this paper the authors have tried to fill this gap by analysing the potential of city break clubbing tourism in Wrocław, the city which has been selected the European Capital of Culture 2016. As part of the analysis, the following elements affecting the development of this type of tourism were examined: transport accessibility, clubbing infrastructure (discos, nightclubs and pubs), and other factors (accommodation facilities and selected tourist attractions). The transport accessibility data include only regular direct flights carried by low-cost carriers (LCC) in 2014 (number of connections, frequency of flights and ticket prices), as this type of transportation is crucial for city break tourism

Teacher Self-Improvement: A Promising Approach to Professional Development and School Improvement

Teacher self-improvement is a promising approach to explore as schools plan to meet the professional development needs of their staff. In this article we focus on: 1) the basic concept of teacher self-improvement, 2) the relationship between teacher self-improvement and teacher evaluation, 3) the categories of information which can be examined during the self-improvement process, 4) some strategies for teacher self-assessment, 5), the process of planning a teacher self-improvement program, and 6) the role of self-improvement in facilitating school improvement

Using Teacher Self-Assessment to Identify Staff Development Needs

The article discusses the study which applies the Johari Window model during the teacher self-assessment process to identify the development needs of teachers in the United States. Staff development programs are successful when the outcomes being fostered are relevant to the teachers\u27 needs
