Operators in Rigged Hilbert spaces: some spectral properties
A notion of resolvent set for an operator acting in a rigged Hilbert space
\D \subset \H\subset \D^\times is proposed. This set depends on a family of
intermediate locally convex spaces living between \D and \D^\times, called
interspaces. Some properties of the resolvent set and of the corresponding
multivalued resolvent function are derived and some examples are discussed.Comment: 29 page
Soft Concurrent Constraint Programming
Soft constraints extend classical constraints to represent multiple
consistency levels, and thus provide a way to express preferences, fuzziness,
and uncertainty. While there are many soft constraint solving formalisms, even
distributed ones, by now there seems to be no concurrent programming framework
where soft constraints can be handled. In this paper we show how the classical
concurrent constraint (cc) programming framework can work with soft
constraints, and we also propose an extension of cc languages which can use
soft constraints to prune and direct the search for a solution. We believe that
this new programming paradigm, called soft cc (scc), can be also very useful in
many web-related scenarios. In fact, the language level allows web agents to
express their interaction and negotiation protocols, and also to post their
requests in terms of preferences, and the underlying soft constraint solver can
find an agreement among the agents even if their requests are incompatible.Comment: 25 pages, 4 figures, submitted to the ACM Transactions on

Research focusing on plant performance in constructed wetlands and agronomic application of treated wastewater – A set of experimental studies in Sicily (Italy)
Constructed wetlands are sustainable technologies for the treatment of wastewater. These biological systems have been widely studied throughout the world for more than 30 years; however, most studies have focused on the effects of design and engineering on pollutant removal from wastewater. Undoubtedly, agro-technical aspects have been given too little consideration by research. This paper reports the main results of a set of experiments carried out on two pilot horizontal subsurface flow systems in Sicily (Italy). Festuca, Lolium and Pennisetum spp. in combination and three emergent macrophytes–Arundo donax L., Cyperus alternifolius L. and Typha latifolia L.–alone, were assessed. The aim of the study was to demonstrate that, under predetermined hydraulic and design conditions, the choice of plant species and the management of the vegetation can significantly affect the pollutant
removal performance of constructed wetlands. In addition, wastewater (after treatment) can also be used for agricultural purposes leading to increased sustainability in agricultural systems. Arundo and Typha-planted units performed better than Cyperus-planted units in terms of chemical, physical and microbiological contaminant removal. All the species adapted extremely well to wetland conditions. Polyculture systems were found to be more efficient than monocultures in the removal of dissolved organic compounds. The reuse of treated wastewater for the irrigation of open fields and horticultural crops led to significant savings in the use of freshwater and fertilizers. The results of physical-energy characterization of A. donax above-ground plant residues and pellets highlighted the fact that a constructed wetland could also be a potential source of bioenergy

Non-collaborative Attackers and How and Where to Defend Flawed Security Protocols (Extended Version)
Security protocols are often found to be flawed after their deployment. We
present an approach that aims at the neutralization or mitigation of the
attacks to flawed protocols: it avoids the complete dismissal of the interested
protocol and allows honest agents to continue to use it until a corrected
version is released. Our approach is based on the knowledge of the network
topology, which we model as a graph, and on the consequent possibility of
creating an interference to an ongoing attack of a Dolev-Yao attacker, by means
of non-collaboration actuated by ad-hoc benign attackers that play the role of
network guardians. Such guardians, positioned in strategical points of the
network, have the task of monitoring the messages in transit and discovering at
runtime, through particular types of inference, whether an attack is ongoing,
interrupting the run of the protocol in the positive case. We study not only
how but also where we can attempt to defend flawed security protocols: we
investigate the different network topologies that make security protocol
defense feasible and illustrate our approach by means of concrete examples.Comment: 29 page
LISENSI PATEN DALAM KAITANNYA DENGAN PROSES ALIH TEKNOLOGI MENURUT UNDANG-UNDANG NOMOR 14 TAHUN 2001
Tujuan dilakukannya penelitian ini adalah untuk mengetahui bagaimana bentuk lisensi paten sebagai sarana alih teknologi dan bagaimana pengaturan alih teknologi dalam Undang-Undang Nomor 14 Tahun 2001 tentang Paten. Dengan menggunakan metode penelitian yuridis normatif, disimpulkan: 1. Lisensi paten mempunyai pengaruh terhadap kehidupan ekonomi suatu negara sebab selain memberikan keuntungan bagi pemilik paten, lisensi paten sangat erat dengan proses terjadinya alih teknologi yang mempunyai manfaat bagi pemegang dan penerima lisensi. Bagi negara berkembang khususnya Indonesia banyak mendapatkan manfaat dengan adanya alih teknologi karena bisa lebih maju dalam bidang teknologi dalam semua bidang. Setiap adanya lisensi paten prosesnya harus didaftarkan agar diketahui sejauh mana manfaat bagi pemilik paten bahkan penerima lisensi paten. 2. Dalam Undang-Undang No. 14 Tahun 2001 tentang Paten karena Indonesia telah meratifikasi semua ketentuan dalam HAKI termasuk paten maka peraturan yang berlaku yaitu baik ketentuan-ketentuan Nasional dan ketentuan-ketentuan internasional. Alih teknologi sangat menguntungkan bagi sipemegang sebab mendapatkan royalty yang banyak dari hasil penjualan bahkan dalam investasi membuka pasar eksport dan dapat terjadi untuk perluasan pasar diluar negeri, menciptakan pasar luar negeri serta menghindari biaya yang sangat mahal dan juga untuk kepentingan riset dan pengembangan suatu daerah. Kata kunci: Lisensi, paten, alih teknolog
An agronomic evaluation of new safflower (Carthamus tinctorius L.) germplasm for seed and oil yields under Mediterraean climate conditions
Interest in oilseed crops for agro-industrial research and development projects has increased in the Mediterranean area, in recent years. Saffloower (Carthamus tinctorius L.) is of potential interest for agriculture mainly due to fatty acid content variability in the seed oil. The aim of this study was to assess the agronomic performance of 16 new safflower accessions together with safflower variety Montola 2000, used as a reference, in a semi-arid environment. Research was carried out in Sicily (Italy) from 2013–2014. Hierarchical cluster analysis carried out on the fatty acid composition of safflower accessions resulted in their division into four main groups. Linoleic, oleic and palmitic acids were the main fatty acids present in the accessions. Seed yield was 1.11 t ha-1 on average and seed oil content was found to be approximately 35.01% of dry matter on average. Positive and significant relationships between seed/oil yield and other tested traits were found. The carbon, hydrogen and nitrogen content as a percentage of dry matter varied greatly both for the above- and belowground
plant parts on average. This study confirms the interest of safflower for both food and non-food applications, offering interesting prospects in semi-arid regions
