Abstract Self-healing on pavement is solution to reduce the handling of road damage without doing heavy construction. Calcium Alginate capsules are mixed in AC-WC (Asphalt Concrete Waring Coarse) Asb Lawele as an added ingredient healing from cracks. Marshall Test specification reference assess can use Asphalt Concrete. Optimum Content 6.2% used make Modification Mix with Alginate. contains 2% ...

In 1940, Ulam [1] proposed the following stability problem: “When is it true that a function which satisfies some functional equation approximatelymust be close to one satisfying the equation exactly?” Next year, Hyers [2] gave an answer to this problem for additive mappings between Banach spaces. Furthermore, Aoki [3] and Rassias [4] obtained independently generalized results of Hyers’ theorem...

In this study, fourteen sustainable concrete mixes containing metakaolin (MK) as supplementary cement material (SCM) and magnetized water (MW) mixing were designed, prepared, tested, analyzed, compared. The MK was used a partial replacement of weight by 5%, 10%, 20%, an additive to 20% weight. MW fully replace tap (TW) in prepared using two different magnetic fields 1.4 tesla (T) 1.6 T. This ex...

background: in megavoltage radiotherapy rooms, ordinary concrete is usually used due to its low construction costs, although higher density concrete are sometimes used, as well. the use of high-density concrete decreases the required thickness of the concrete barrier hence, its disadvantage is its high cost. in a nuclear reactor, neutron radiation is the most difficult to shield. a method for p...

Surfaces of carbon fibre roving were modified by means of a low temperature plasma treatment to improve their bonding with mineral fines; the latter serving as an inorganic fibre coating for the improved mechanical performance of carbon reinforcement in concrete matrices. Variation of the plasma conditions, such as gas composition and treatment time, was accomplished to establish polar groups o...

The paper gives an overview on the meta-data specification for administrating and enforcing enterprisewide security for heterogeneous and distributed information systems. The meta-data serves as a basis to maintain enterprise-wide security information centrally, to integrate isolated security specifications, to keep the consistency between different security policies, and to perform access cont...

This paper addresses the security of public-key cryptosystems in a \multi-user" setting, namely in the presence of attacks involving the encryption of related messages under di erent public keys, as exempli ed by H astad's classical attacks on RSA. We prove that security in the single-user setting implies security in the multi-user setting as long as the former is interpreted in the strong sens...
