PCM Thermal Energy Storage Systems; Ashrae 2004 Conference PaperZafer Ure
Thermal Energy Storage (TES) may be considered as a useful tool to reduce the number of refrigeration machinery by means of spreading the daytime load over 24 hours period. Hence, any type of TES systems can be consider as useful tool to reduce the overall environmental impact for a given cooling application.
This paper explores the use of eutectic, phase change materials for TES systems.
This presentation describes how use of judiciously selected Phase Change Materials can be used effectively to store energy and make it available when needed.
In a solar thermal application, typically sunlight is available in a 6-8 hour window from 8am to 4pm. However, the usage extends much beyond that. Phase Change Materials can be used to store energy for usage as required.

This study offers an overview of the technologies for hydrogen production especially alkaline water electrolysis using solar energy. Solar Energy and Hydrogen (energy carrier) are possible replacement options for fossil fuel and its associated problems of availability and high prices which are devastating small, developing, oil-importing economies. But a major drawback to the full implementation of solar energy, in particular photovoltaic (PV), is the lowering of conversion efficiency of PV cells due to elevated cell temperatures while in operation. Also, hydrogen as an energy carrier must be produced in gaseous or liquid form before it can be used as fuel; but its‟ present major conversion process produces an abundance of carbon dioxide which is harming the environment through global warming. Alkaline water electrolysis is considered to be a basic technique for hydrogen production. In the present study, the effects of electrolyte concentration, solar insolation and space between the pair of electrodes on the amount of hydrogen produced and consequently on the overall electrolysis efficiency are experimentally investigated. The water electrolysis of potassium hydroxide aqueous solution was conducted under atmospheric pressure using stainless steel 316 as electrodes.
The experimental results showed that the performance of alkaline water electrolysis unit is dominated by operational parameters like the electrolyte concentration and the gap between the electrodes. Smaller gaps between the pair of electrodes and was demonstrated to produce higher rates of hydrogen at higher system efficiency
This study shows some attempts to product pure Hydrogen and pure Oxygen as both Hydrogen and Oxygen have there commercial demands.

Transporti me litare, perfshine ato lloje te transporti ne te cilen objekti qe transportohet c’vendoset me ndihmen e nje litari. Kjo eshte konceptuar ne terheqjen e mjetit mbartes me anen e litarit, pergjate udhes se tij, ose shtriries se tij. Historikisht tipike, ky lloj transporti perfaqesonte levizjet e mjeteve lundruese, mbi lumenj ose kanale lundruese. Sot ky lloj transporti (lumenj lundruese) eshte gjeneruar ne forma te ndryshme, sic do ta shohim ne leksionet e meposhteme. Peshen kryesore ne kete lloj transporti e ze transporti me teleferik dhe ai me ashensore, (pa permendur makinat ngritese-transportuese). Transporti me terheqje rreshqanthi, pergjate tokes, eshte pak i perhapur. (Ekzistojne studime te cilat tentojne te perfshijne kete lloj transporti, te permendur ne fund, ne formen e linjave me shina, si nje forme e transportit urban ne qytetet e medha dhe me infrastrukture te dobed). Ne ne leksionin tone do te trajtojme transportin me teleferik, dhe ai me ashensore, si dy forma transporti me mundesi perhapje ne Shqiperi. Per transportin me makina peshengritese-transportuese, nuk do ti trajtojme, per specifikat e vecanta te tyre, si dhe per detyren qe ne kemi vene ne lenden tone, Transportin publik
Kerkesa per parkim
Karakteristika e problemeve te transportit
Parkimi eshte nje aspekt i rendesishem i transportit qe ndihmon (pranon) ne praktike levizjen e automjeit. Ne qendrat urbane politika e vendqendrimeve te inspirohet nga kritere dhe objektiva te ndryshme , por ne cdo rast p[ermban nje total racionale e bazuar ne njohjen e ofertes ne veprim dhe kerkeses me te gjitha kuptimet sasiore e cilesore. Vleresimi i ofertes eshte nje problem i nje vezhgimi te paster statistikore ndersa kerkesa varion ne hapsire dhe ne kohen dhe mbi gjithshka ne sjelljen e perdoruesave ne lidhjen me politiken e pergjitheshme dhe ne vecanti me vete politiken e vendqendrimeve. Ne kete kapitull do te mundohemi te ndertojme tek disa modele te vleresimit te kerkeses, ne vecanti tek modeli gravitacional , dhe do te dallohen disa parametra qe bejne matjen e kerkeses per parkim.
Po te levizjen per sherbim transporti si nje rryme fluidi (ajri/lengu), dhe infrastrukturen si nje labirinth tubash, me pike fillimi, mbarimi, si dhe interseksione te ndryshme, ku neper kete sistem tubash kalon fluidi ne fjale. Eshte e kuptueshme qe per kontrollin ose komandimin e rastit, te vendosen disa elemente konstruktive, te cilet disiplinojne kalimin e fluidit neper nje, ose disa tuba te vecante, ose te lidhur ne njefare sistemi. Keshtu me kete lloj perfytyrimi qe ne po krijojme, mund ta njehsojme levizjen kaotike neper infrastrukture, te perdoruesave te mjeteve (shofere transporti mallrash, ose pasagjeresh, ose qytetare perdorues te mjeteve private, te cilet levizin neper infrastrukturen ekzistuese, per te realizuar nje cvendosje nga nje pozicion ne nje tjeter). Ne q. se vazhdojme te krahasojme situacionin e mesiper, ne llidhje me nje fluid vleresohen parametrat cilesor te tij si:, temperaturat dhe vetit e fizike te tij, vizkoziteti, pasha specifike, shpejtesia etj. Te cilat vleresojne levizjen e fluidit ne keto tubacione. Ne nje sistem transporti levizja e perdoruesave te infrastruktures ne nje intinerar mund te vleresohet nga disa parametra ose karkateristikat e fluksit te perdoruesave, te cilat mund te grupojme 3 faktore qe influencojne direkt per kete fenomen, ose levizje. Mjeti-drejtuesi-ambjenti, te tre keto grupime jane elmente perberes dhe influencues ne cdo lloj levizje mjetesh ne te gjithe infrastrukturen.
Ne c’do projekt transporti, ne aspektin e trajtimit te skemes klasike, sic quhet teknologjia e transportit (ai i transportit te objektit nga nje vend ne nje tjeter),.kemi kete perberje ne procesin teknologjik :
Levizja e objektit (mall ose njerez) me mjetin mbartes. Ne kapitujt e mesiperm ne i kemi permendur keto lloj mjetesh te cilet percaktojne dhe llojin e transportit, konkretisht kane keto emertime:
• transporti automobilistik (mjeti eshte automobili)
• transporti detare e lumore (mjeti eshte lundra, varka)
• transporti hekurudhore (mjeti eshte vagoni i terhequr me lokomotive )
• transporti airore (mjeti eshte aeroplani, helikopteri, balona, )
• transporti me litare (mjeti eshte teleferiku, ashensori, ose c’do makine ngritese transportuese)
Nganjehere kerkohet te parashikohet nje perspektive e zhvillimit te transportit, ose te ristrukturohet ne drejtim te permiresimit te parametrave, nje sistemi transporti. Keshtu, mund dhe duhet te behen, ridimensionimet gjenerale te modeleve matematikore, ose te relacioneve matematikore te bashkangjitura keto projektit te sistemit te transportit. Sa me siper, mund te shprehim ne forme te pergjitheshme :
Tij* = ( fk1,fk2,...fkn )= f(A,B,C,...,M) ku :
T fluksi i spostimeve ndaj 2 zonave i-j dhe me karakteristikat e ketij fluksi fk1,..fkn. te cilat japin funksionet relative A,B,C,... per sistemin e transportit.
Eshte e domosdoshme te sqarojme se, ne evolucionin e kerkeses per transport, futen parametra me te dukshme, ndersa te tjerat nuk perfillen, per vete natyren diskrete, te ketyre rasteve, ky fakt e ben qe, here pas here te rishikohen vleresimet, per zgjidhjen e sistemit kzistues, (sepse faktoret ndryshojne, si koha/ kosto/ distanca e levizjes me kemb/ parkimi/ komoditeti etj.). Ne perdorimin e modelit matematik, per nje sistem transporti, praktikisht behet nje thjeshtim i realitetit, gje qe zgjidhjet optimale duhen te merren duke i permiresuar here pas here parametrat e nje sistemi transporti, ne perputhje me kushtet aktualehere.
Si duhet ta shikojme/studjojme rrealisht nje statistike ne fushen e transportitAlbania Energy Association
Elementi baze ne ndertimin e nje projekti transporti eshte analiza e kerkes-ofert per transport. Kjo shpesh vjen nga verejtjet, ose pamjat direkte ne terren, nga menyra se si sillen ose levizin njerezit apo mallrat. Ashtu si dhe ne vleresimet e tjera per terrenin, edhe ketu kemi nje logjike te perafert, e dalluar, si me poshte:
1) Niveli i sherbimit mbi infrastrukturen ekzistuese, kjo ka te beje me grumbullimin e te dhenave rreale, statistikore mbi infrastrukturen ekzistuese, si dhe kerkesen per transport, apo sherbimet e transportit, si dhe pyetjet ose ceshtjet te tjera, qe lindin ne kete bashkeveprim kerkese-oferte
2) Modelimi simulues i nje sistemi, ne te cilen jane parashikuar vleresimet tekniko-ekonomike, nder te tjerat dhe demografike, social-ekonomike, urbanistike, etj. Si kane ndikuar ose vijuar keto elemente, gjate shfrytezimit ?
3) Treguesit Financiare, si kane qene dhe si eshte bilanci financiare i ketij sherbimi, dinamika e tij, si dhe ndonje alternative e tij, ne pasqyren e kostove e te rendimentit
Per ndertimin e nje projekt transporti, duhet detyrimisht te merren ne konsiderate shume elemente, ose kushte, te cilat konvertohen ne nje bashkesi ndervaresie e quajtur Modeli i sistemit te transportit, ky model eshte i afte ti simuloje keto kushte apo elemente, te projektit duke ne dhene rezultatet respektive. Sa me siper, nje projekt per nje sistem transporti, duhet te ece neper keto faza logjike:
Individualizimi i objeketve qe kerkojne levizje (kerkesa per transport)
Analiza sasiore e sistemit te transportit aktual (ose per disa sisteme)
Ndertimi i nje model varesie, qe perfaqeson nje sitem transporti, i cili eshte ne gjendje te funksionoje me te dhenat (dati) aktuale, si edhe me parametrat e vlerave te prespektives, ne lidhje me kete sistem qe po projektojme, se bashkeu me sistemet e tjere konkurues
Pergjithesime
Nje nder problemet qe e veshtiresojne shperndarjen, shtririen e transportit te mallrave mbi rruge, eshte koha e madhe jo levizese e mallit, ne pikat e nderthuries se levizjeve (grumbullimin, shperndarjen, vazhdim levizjeje te mallit ne destinacion) e cila presupozon kohen e perpunimit te mallit. Si dhe siperfaqet e disponueshme per kete kohe ne keto pika te nderthurjes se levizjes e te perpunimit te mallrave. Keshtu mga viti 1930-40 filloj nje koncep i ri “unifikimi i njesive te ngarkesave” kjo do te thote qe menyra te ambalazhimit te jete e paraqykyar qe ne projektim si nje element ne teknologjine e organizimit te transportit te objektit, kjo gje solli qe:

Effective Application Security in Software Delivery lifecycle using Deployment Firewall and DBOM
The modern software delivery process (or the CI/CD process) includes many tools, distributed teams, open-source code, and cloud platforms. Constant focus on speed to release software to market, along with the traditional slow and manual security checks has caused gaps in continuous security as an important piece in the software supply chain. Today organizations feel more susceptible to external and internal cyber threats due to the vast attack surface in their applications supply chain and the lack of end-to-end governance and risk management.
The software team must secure its software delivery process to avoid vulnerability and security breaches. This needs to be achieved with existing tool chains and without extensive rework of the delivery processes. This talk will present strategies and techniques for providing visibility into the true risk of the existing vulnerabilities, preventing the introduction of security issues in the software, resolving vulnerabilities in production environments quickly, and capturing the deployment bill of materials (DBOM).

zkStudyClub - Reef: Fast Succinct Non-Interactive Zero-Knowledge Regex ProofsAlex Pruden
This paper presents Reef, a system for generating publicly verifiable succinct non-interactive zero-knowledge proofs that a committed document matches or does not match a regular expression. We describe applications such as proving the strength of passwords, the provenance of email despite redactions, the validity of oblivious DNS queries, and the existence of mutations in DNA. Reef supports the Perl Compatible Regular Expression syntax, including wildcards, alternation, ranges, capture groups, Kleene star, negations, and lookarounds. Reef introduces a new type of automata, Skipping Alternating Finite Automata (SAFA), that skips irrelevant parts of a document when producing proofs without undermining soundness, and instantiates SAFA with a lookup argument. Our experimental evaluation confirms that Reef can generate proofs for documents with 32M characters; the proofs are small and cheap to verify (under a second).

Cooling Choices
Direct Condensing (Conduction)
Evaporative (Cooling Tower)
Natural Convection
Diagram of a typical water-cooled surface condenser
Requires nearby river or lake
If limit on ΔT= 10°C,
water req’d = (1E13 cal/day)/10°C
=1E9 kg water/day = 1E6 m3/day
= 264 million gallons/day
= 410 cubic feet per second
(The St. Louis River at Scanlon has
a 100-yr mean flow of 1060 cfs).
Forced Convection
For latent heat of evaporation of water
of 540 cal/g, and
Assuming 1E13 cal/day of cooling,
need 1.85 E10 grams of water/day
or ~ 5 million gallons/day
Direct – 264 E6 gal/day – water conserved
Evaporative – 5 E6 gal/day – water lost

13. Synthetic Fuels
(Syn Fuels or Alternative Fuels)
• Alternative to Petroleum-derived fuels
– Interest proportional to fear of import disruption
– Attractive due to lower sulfur, carbon mgmt.
• Input: Coal, biomass, oil shale

17. More Notes on Combustion
• Heat released used to combust more fuel
• Combustion dominates fossil fuel conversion
• Combustion dominates anthropogenic CO2 emissions to
atmosphere
• Combustion creates diverse pollutants
• Stationary technology well developed, controlled
• Revolutionary advances unlikely
• Combustion requires:
–
–
–
–
Contact between fuel and oxidant molecules
Reactants must be heated to be able to react “fast enough”
Reaction must last “long enough” to allow complete reaction
Three T’s: turbulence, temperature, time
17
18. Fuel Cells
• Hydrogen + Oxygen = electricity + water + heat
• Oxidation occurs, but not as fast as in combustion
• Why not directly convert chemical energy to electrical
energy (with up to 75% efficiency), than be limited by
thermodynamic conversion efficiencies of 35 to 40%?)
• Today’s technology most promising for vehicles
18
19. Fuel Cells
• Zero Emission Vehicles (ZEVs) relied primarily on
batteries prior to 2003; then, litigation in California shifted
work to fuel cells; 5 of 6 automakers abandoned
batteries temporarily
• Today: fuel cells 20 times more costly than IC engine;
last three years, hydrogen storage problems, no stations
• Carmakers propose making 2500-5000 fc vehicles by
2014

20. Fuel Cells
Basic fuel cell:
2H2(gas) + O2(gas)→ 2H2O
Separate into half reactions at each electrode:
H2 + 2OH- → 2H2O + 2e-Anode
O2 + 2H2O + 4e- → 4OH-
Cathode

“Electrons always flow from anode to cathode outside the device, regardless
of device type”
21
22. Fuel Cells
H2
O2
Supply H and O to cell
But need to separate gases, while
allowing movement of electrons
and ions between electrodes
Porous partition or membrane used
Hydrogen gives up electrons on the left (electrons flow out of cell),
making the left electrode the Anode
Hydrogen is oxidized at the Anode
On the right, the negatively charge ions (anions) that result from
the reduction of oxygen flow to the left (cathode to anode) through
the electrolyte and the membrane
The electrolyte conducts charged particles much larger than electrons,
and can be a liquid or solid. A “solute” that produces a conducting
22
solution is an “electrolyte” (e.g., acids, sodium chloride)
23. Fuel Cells
Advantages
• Low maintenance, high reliability if stationary
• Low noise level, only emission is water
• Can stack and parallel cells for V and I
Disadvantages
• Poor voltage regulation (drops under load)
• Best for applications with steady loads
• High cost, durability in changing environments, weight
• Cost effectively supplying the hydrogen
• Matching rate of hydrogen supply to cell load
