A computer program for the generation of logic networks from task chart data

The Network Generation Program (NETGEN), which creates logic networks from task chart data is presented. NETGEN is written in CDC FORTRAN IV (Extended) and runs in a batch mode on the CDC 6000 and CYBER 170 series computers. Data is input via a two-card format and contains information regarding the specific tasks in a project. From this data, NETGEN constructs a logic network of related activities with each activity having unique predecessor and successor nodes, activity duration, descriptions, etc. NETGEN then prepares this data on two files that can be used in the Project Planning Analysis and Reporting System Batch Network Scheduling program and the EZPERT graphics program

Production version of the extended NASA-Langley Vortex Lattice FORTRAN computer program. Volume 1: User's guide

The latest production version, MARK IV, of the NASA-Langley vortex lattice computer program is summarized. All viable subcritical aerodynamic features of previous versions were retained. This version extends the previously documented program capabilities to four planforms, 400 panels, and enables the user to obtain vortex-flow aerodynamics on cambered planforms, flowfield properties off the configuration in attached flow, and planform longitudinal load distributions

Boosting the Kerr-geometry into an arbitrary direction

We generalize previous work \cite{BaNa3} on the ultrarelativistic limit of the Kerr-geometry by lifting the restriction on boosting along the axis of symmetry.Comment: latex2e, no figure

Closed-loop approach to thermodynamics

We present the closed loop approach to linear nonequilibrium thermodynamics considering a generic heat engine dissipatively connected to two temperature baths. The system is usually quite generally characterized by two parameters: the output power $P$ and the conversion efficiency $\eta$, to which we add a third one, the working frequency $\omega$. We establish that a detailed understanding of the effects of the dissipative coupling on the energy conversion process, necessitates the knowledge of only two quantities: the system's feedback factor $\beta$ and its open-loop gain $A_{0}$, the product of which, $A_{0}\beta$, characterizes the interplay between the efficiency, the output power and the operating rate of the system. By placing thermodynamics analysis on a higher level of abstraction, the feedback loop approach provides a versatile and economical, hence a very efficient, tool for the study of \emph{any} conversion engine operation for which a feedback factor may be defined

A Revised List of the Orthoptera of Iowa

The first list of Iowa Orthoptera was entitled A Preliminary Catalogue of the Orthoptera of Iowa. This was published by C. E. Bessey in the Seventh Biennial Report of the Iowa State College in 1877. The list included about forty species

Kajian Implementasi E-learning Berdasarkan Tingkat Kesiapan Peserta E-learning

Implementasi sistem e-learning banyak dilakukan di beberapa institusi termasukFPMIPA UPI. Evaluasi dan pengukuran kesiapan peserta e-learning pun mulaibanyak dilakukan. Penelitian ini bertujuan untuk mengkombinasikan empatkategori kesiapan peserta e-learning yang diadopsi dari penelitian-penelitiansebelumnya sebagai upaya menemukan model pengukuran yang ideal. Keempatkategori kesiapan merupakan kombinasi dari akses teknologi, keahlian internetdan komputer, motivasi serta gaya belajar yang kemudian dibuat ke dalamsebuah model struktural beserta 17 indikator penyusunnya. Pengumpulan datadilakukan dengan menggunakan kuesioner online yang dibangun berdampingandengan model. Selanjutnya model dikonfirmasi menggunakan teknik analisismodel persamaan struktural dengan jumlah responden 223 orang yang terdiridari mahasiswa tingkat tiga dan empat. Dari hasil analisis berbantuan perangkatlunak analisis SEM didapati bahwa model berhasil divalidasi dan keempatkategori terbukti memiliki hubungan. Dengan skala pengukuran Aydin dan Tasci(2005) didapati derajat kesiapan peserta e-learning berada pada tingkat ‘belumsiap namun hanya memerlukan sedikit persiapan untuk e-learning

Relativistic Effects in Nuclear Matter and Nuclei

The status of relativistic nuclear many-body calculations of nuclear systems to be built up in terms of protons and neutrons is reviewed. In detail, relativistic effects on several aspects of nuclear matter such as the effective mass, saturation mechanism, and the symmetry energy are considered. This review will especially focus on isospin asymmetric issues, since these aspects are of high interest in astrophysical and nuclear structure studies. Furthermore, from the experimental side these aspects are experiencing an additional boost from a new generation of radioactive beam facilities, e.g. the future GSI facility FAIR in Germany or SPIRAL2 at GANIL/France. Finally, the prospects of studying finite nuclei in microscopic calculations which are based on realistic $NN$ interactions by including relativistic effects in calculations of low momentum interactions are discussed.Comment: 57 pages, 16 figure
