Abstract

The collection of ancient coins of the Palacký University in Olomouc is recently preserved in the department of history there. It is very likely that the collection was founded sometimes between the second half of the 19th century and the beginning of the 20th century – no details are known about it and the collection became the university property evidently after 1946. The core of the Olomouc collection is represented by denarii dating back to 154–74 BC (cat. nos. 3–69). Only individual pieces of the earlier issues (cat. nos. 1–2) and the later issues (cat. nos. 70–72) are present here. Publication of this collection could be accepted as a small contribution to documentation of the physically verified material of the mentioned period. Parallelly, it is an interesting testimony of the collecting activities in Olomouc at the break of the 19th and 20th centuries.

Abstract

We formalize and construct black-box accumulation (BBA), a useful building block for numerous important user-centric protocols including loyalty systems, refund systems, and incentive systems (as, e.g., employed in participatory sensing and vehicle-to-grid scenarios). A core requirement all these systems share is a mechanism to let users collect and sum up values (call it incentives, bonus points, reputation points, etc.) issued by some other parties in a privacy-preserving way such that curious operators may not be able to link the different transactions of a user. At the same time, a group of malicious users may not be able to cheat the system by pretending to have collected a higher amount than what was actually issued to them.

As a first contribution, we fully formalize the core functionality and properties of this important building block. Furthermore, we present a generic and non-interactive construction of a BBA system based on homomorphic commitments, digital signatures, and non-interactive zero-knowledge proofs of knowledge. For our construction, we formally prove security and privacy properties. Finally, we propose a concrete instantiation of our construction using Groth-Sahai commitments and proofs as well as the optimal structure-preserving signature scheme of Abe et al. and analyze its efficiency.

A simple technique of random leaf collecting for biometric studies in a tree stand

The method reflects proportions in the number of leaves of different sizes and shapes, which appear in a tree stand. The study was carried out during autumn leaf fall, in about a hundred years old tree stand, dominated by beech. Leaves were collected three times, altogether with assessment of foliage density. For all gathered leaves, the width and length were measured and the data were statistically analyzed. Differences among all three samples were significant, which indicates different size of falling leaves in the following periods. Thus, only the research carried on at the end of leaves falling allows collecting a sample which represents proportions among leaves of different sizes in the tree stand.

Abstract

This paper describes for the first time an original foggara, different from the classical foggara (foggara of Gourara) which collects water from the Intercalary Continental aquifer. Located in the middle of the Mzab River, this hydraulic system called the Mzab foggara is intended to exploit the flood waters. Two missions were carried in 2009 and 2010 in the Mzab Valley to describe the hydraulic system. The Mzab foggara constitutes of a gallery of ovoid form 200 m long equipped with 9 air shafts and a 900 m long seguia. The foggara of the Mzab River can drain water flow of 5 m3·s-1 to irrigate western part of the palm plantation of Ghardaia (located 600 km south of Algiers).

Abstract

New faunistic data on the distribution of 50 species of the family Agromyzidae from the Afrotropical Region are given. Chromatomyia syngenesiae Hardy, 1849 and Phytomyza ranunculi (Schrank, 1803) are firstly recorded for the Afrotropics and 47 species are firstly recorded for the following countries: Angola, Cameroon, Cape Verde Islands, Central African Republic, Ethiopia, Kenya, Madagascar, Malawi, Namibia, Nigeria, Sierra Leone, Somalia, Tanzania, Uganda, Zambia, Zimbabwe. For each country the number of known species are put together in a table. An updated Afrotropical checklist is added. The most peculiar genitalia of the redetected Ophiomyia dhofarensis are discussed in connection with other species, among them: Ophiomyia yunnanensis comb. nov. [= Ophiomyia dumosa syn. nov.]. Ophiomyia nigrimaculata comb. nov. is treated taxomically, too. The type-species of the Pseudonapomyza acanthacearum-group is re-defined. Ranunculus was firstly confirmed as host plant genus of Phytomyza subeximia which develops between its seeds, a rare substrate in the genus. Napomyza strana stat. rev. was redetected in an altitude of 3353 m a.s.l. An eclector collecting method is described which lets estimate the natural proportional abundance of Agromyzidae compared with all other Diptera in the groundlevel vegetation of a country.
