Analisis Kesalahan Penggunaan Frasa pada Tajuk Rencana Surat Kabar Kompas
Surat kabar, sebagai media informasi yang dibaca oleh berbagai kalangan, memiliki peran penting dalam perkembangan bahasa sebuah bangsa. Sementara itu, pada surat kabar daerah atau nasional yang beredar, masih ditemukan kesalahan dalam penggunaan frasa. Kesalahan pun terjadi pada koran nasional setingkat Kompas. Kesalahan tersebut terjadi karena kurangnya perhatian terhadap kaidah kebahasaan. Oleh karena itu, dalam penelitian ini dikaji tentang kesalahan penggunaan frasa pada tajuk rencana surat kabar Kompas. Pada penelitian ini digunakan metode analisis isi (content analysis) yang bersifat preskriptif. Teknik pengumpulan data yang digunakan adalah teknik dokumentasi dan hermeneutik. Data penelitian bersumber dari tajuk rencana surat kabar harian Kompas yang diambil secara acak. Data yang diteliti didokumentasi dengan cara dibaca, dicatat, selanjutnya disimpulkan, dan dikelompokkan berdasarkan kesalahan yang terdapat dalam bidang frasa. Berdasarkan analisis, kesalahan penggunaan frasa pada tajuk rencana surat kabar Kompas adalah penggunaan unsur yang berlebihan atau mubazir dan penggunaan preposisi yang tidak tepat
Robustness of the BB84 quantum key distribution protocol against general coherent attacks
It is demonstrated that for the entanglement-based version of the
Bennett-Brassard (BB84) quantum key distribution protocol, Alice and Bob share
provable entanglement if and only if the estimated qubit error rate is below
25% or above 75%. In view of the intimate relation between entanglement and
security, this result sheds also new light on the unconditional security of the
BB84 protocol in its original prepare-and-measure form. In particular, it
indicates that for small qubit error rates 25% is the ultimate upper security
bound for any prepare-and-measure BB84-type QKD protocol. On the contrary, for
qubit error rates between 25% and 75% we demonstrate that the correlations
shared between Alice and Bob can always be explained by separable states and
thus, no secret key can be distilled in this regime.Comment: New improved version. A minor mistake has been eliminate
Completely positive covariant two-qubit quantum processes and optimal quantum NOT operations for entangled qubit pairs
The structure of all completely positive quantum operations is investigated
which transform pure two-qubit input states of a given degree of entanglement
in a covariant way. Special cases thereof are quantum NOT operations which
transform entangled pure two-qubit input states of a given degree of
entanglement into orthogonal states in an optimal way. Based on our general
analysis all covariant optimal two-qubit quantum NOT operations are determined.
In particular, it is demonstrated that only in the case of maximally entangled
input states these quantum NOT operations can be performed perfectly.Comment: 14 pages, 2 figure
Kohesi Teks Syair Dalam Tunjuk Ajar Melayu Karya Tenas Effendy
Research on the cohesion of poetical text in Tunjuk Ajar Melayu by Tenas Effendy which viewed from the aspect of language. The role of cohesion is necessary in a text to support the linkage between the stanza with the stanza and the array with the array in a poem. With the cohesion will make it easier to read understand the author\u27s intent. Cohesion can also affect the level of appreciation and understanding of the reader or the listener. Therefore, this study aims to know the cohesion between the lines in one line and antarbait in the text of the teachings of the teachings of Tenas Effendy Malay. The theory used Tarigan (1993), Effendy (2013), Tarigan (2009) and other supporting theories. Writing research this is descriptive-analitik with qualitative descriptive method. The data of this research are sourced Tunjuk Ajar Melayu by Tenas Effendy in 2013. Based on the research findings, there are several cohesion tools used in the text of lecture of Tenas Effendy\u27s Malay teaching, among others, pronouncement, substitution, conjunction and lexical cohesion. There are several ways of lexical used are repetition, synonym and antonym and so on
Wave Solutions of Evolution Equations and Hamiltonian Flows on Nonlinear Subvarieties of Generalized Jacobians
The algebraic-geometric approach is extended to study solutions of
N-component systems associated with the energy dependent Schrodinger operators
having potentials with poles in the spectral parameter, in connection with
Hamiltonian flows on nonlinear subvariaties of Jacobi varieties. The systems
under study include the shallow water equation and Dym type equation. The
classes of solutions are described in terms of theta-functions and their
singular limits by using new parameterizations. A qualitative description of
real valued solutions is provided
Efficient bipartite quantum state purification in arbitrary dimensional Hilbert spaces
A new purification scheme is proposed which applies to arbitrary dimensional
bipartite quantum systems. It is based on the repeated application of a special
class of nonlinear quantum maps and a single, local unitary operation. This
special class of nonlinear quantum maps is generated in a natural way by a
hermitian generalized XOR-gate. The proposed purification scheme offers two
major advantages, namely it does not require local depolarization operations at
each step of the purification procedure and it purifies more efficiently than
other know purification schemes.Comment: This manuscript is based on results of our previous manuscript
