Loosely Synchronised Spreading Code Aided Network Performance of Quasi-Synchronous UTRA-like TDD and FDD CDMA Systems

It is demonstrated that loosely synchronised (LS) spreading codes exhibit a so-called interference-free window, where both the autocorrelation and cross-correlation of the codes become zero. Therefore LS codes have the promise of mitigating the effects of both inter-symbolinterference and multiple-access-interference in time dispersive channels. Hence, LS codes have the potential of increasing the capacity of CDMA networks. The work reported has studied the achievable network performance and compared it to that of a UTRA-like time division duplex (TDD) and frequency division duplex (FDD) CDMA system using orthogonal variable rate spreading factor codes

Loosely synchronized spreading code aided network performance of quasi-synchronous UTRA-like TDD/CDMA systems

In this paper we investigate the achievable capacity of a UTRA-like Time Division Duplex (TDD) Code Division Multiple Access (CDMA) system employing Loosely Synchronized (LS) spreading codes. The family of operational CDMA systems is interference limited, suffering from Inter-Symbol-Interference (ISI), since the orthogonality of the spreading sequences is destroyed by the frequency selective channel. They also suffer from Multiple-Access-Interference (MAI) owing to the non-zero cross-correlations of the spreading codes. By contrast, the family of LS codes exhibits a so-called Interference Free Window (IFW), where both the auto-correlation and cross-correlation of the codes become zero. Therefore LS codes have the promise of mitigating the effects of both ISI and MAI in time dispersive channels. Hence, LS codes have the potential of increasing the capacity of CDMA networks. This contribution studies the achievable network performance in comparison to that of a UTRA-like TDD/CDMA system using Orthogonal Vari- MSO able Rate Spreading Factor (OVSF) codes

The effect of the motion of the Sun on the light-time in interplanetary relativistic experiments

In 2002 a measurement of the effect of solar gravity upon the phase of coherent microwave beams passing near the Sun has been carried out with the Cassini mission, allowing a very accurate measurement of the PPN parameter $\gamma$. The data have been analyzed with NASA's Orbit Determination Program (ODP) in the Barycentric Celestial Reference System, in which the Sun moves around the centre of mass of the solar system with a velocity $v_\odot$ of about 10 m/sec; the question arises, what correction this implies for the predicted phase shift. After a review of the way the ODP works, we set the problem in the framework of Lorentz (and Galilean) transformations and evaluate the correction; it is several orders of magnitude below our experimental accuracy. We also discuss a recent paper \cite{kopeikin07}, which claims wrong and much larger corrections, and clarify the reasons for the discrepancy.Comment: Final version accepted by Classical and Quantum Gravity (8 Jan. 2008

An optimal gap theorem

By solving the Cauchy problem for the Hodge-Laplace heat equation for $d$-closed, positive $(1, 1)$-forms, we prove an optimal gap theorem for K\"ahler manifolds with nonnegative bisectional curvature which asserts that the manifold is flat if the average of the scalar curvature over balls of radius $r$ centered at any fixed point $o$ is a function of $o(r^{-2})$. Furthermore via a relative monotonicity estimate we obtain a stronger statement, namely a `positive mass' type result, asserting that if $(M, g)$ is not flat, then $\liminf_{r\to \infty} \frac{r^2}{V_o(r)}\int_{B_o(r)}\mathcal{S}(y)\, d\mu(y)>0$ for any $o\in M$

Balinese Customary Consultation Service Unit

Development on tourism sector in Bali Island carried great implication to Balinese costumes and culture. Many cases on Balinese costumes and culture were raised such as costume and culture values infraction, conflict between local community with investor, and others. The present community services were aimed to give consultation in order to solve of many problems related to Balinese customary. The conducted services were giving consultation and assistance to the communities which had problems. Issues raised on the consultation were discussed and publicized to Bali costumes community. The activities of community services were located at Graduate School of Udayana University building, Denpasar. Result showed that this unit has gained a positive response, which indicated by number of people using this services as well as number of books being sold. In ten months, 3000 books have been sold or approximately 300 books per month. Majority (almost 80%) were bought by government institutions, which then distributed it to the community; while the rest 20% were bought by the individual. Meanwhile, in term of services, this unit was able to served 126 clients for consultation. They were mostly local Balinese people (around 80%), 15% were non-Bali citizen, and about 5% were expatriates. And besides those activities, this unit was also provided consultation services in the making of awig-awig (Balines custom regulation) for 3 desa adat in 2011. To sum up, during 10 months of operation, this unit has turnover reached IDR. 217,237,500 or equivalent to IDR 21,723,750 per month, with the following details: 1) sale of books at IDR 124,237,500; 2) consultation services at IDR 63,000,000; and 3) awig-awig consultation services at IDR. 30.000.000,-. Net cash flows, then, reached IDR 46,578,400, and about IDR 4,019,600 of the net cash flows were allocated for institution’s development program

Suggestion from this research that a leader must apply transformational leadership style in order to be able to improve employee work satisfaction, compensation must be given in accordance with work load and achievement of employees, and work environment must be kept comfort and kekondusifannya

Dampak Stock Split Terhadap Reaksi Pasar Pada Perusahaan Yang Terdaftar Di Bursa Efek Indonesia

Stock split merupakan salah satu kegiatan korporasi yang digunakan untuk meningkatkan likuiditas saham. Penelitian ini bertujuan untuk mengetahui perbedaan reaksi pasar saham sebelum dan sesudah stock split dan pengaruh split factor terhadap reaksi pasar. Pemilihan periode peristiwa didasarkan pada panjangnya jumlah pengamatan dan menghindari terjadinya confounding effect. Penelitian ini ditujukan untuk mengetahui reaksi pasar di sepanjang peristiwa stock split. Jika terdapat perbedaan reaksi pasar maka stock split dapat dikategorikan sebagai peristiwa yang mengandung informasi. Penelitian ini mengambil 48 sampel yang melakukan stock split dan terdaftar di Bursa Efek Indonesia pada periode 2010-2014 dengan menggunakan metode sensus. Teknik analisis data yang digunakan adalah Paired Sample t-test dan Regresi Sederhana dengan periode jendela peristiwa selama 11 hari. Hasil penelitian menunjukan bahwa tidak terdapat reaksi pasar saham sebelum dan sesudah stock split dan split factor tidak berpengaruh terhadap reaksi pasar. Berdasarkan hasil pengujian ini menunjukkan bahwa pasar tidak bereaksi terhadap peristiwa stock split

Fermi Coordinates for Weak Gravitational Fields

A Reference is corrected. (We derive the Fermi coordinate system of an observer in arbitrary motion in an arbitrary weak gravitational field valid to all orders in the geodesic distance from the worldline of the observer. In flat space-time this leads to a generalization of Rindler space for arbitrary acceleration and rotation. The general approach is applied to the special case of an observer resting with respect to the weak gravitational field of a static mass distribution. This allows to make the correspondence between general relativity and Newtonian gravity more precise.)Comment: 7 Pages, Preprint KONS-RGKU-94-04, LaTe
